-   lid.  At this point, Xt's timers will fire, and xscreensaver will blank
-   the screen.
-
-   So far so good -- well, not really, but it's the best that we can do,
-   since the OS doesn't send us a signal *before* shutdown -- but if the
-   user had delayed locking (lockTimeout > 0) then we should start off
-   in the locked state, rather than only locking N minutes from when the

-
-   We only do this when we'd be polling the mouse position anyway.
-   This amounts to an assumption that machines with APM support also

-   independently of changes in wall-clock time.  But of course that's not
-   portable.
-
-   When the wall clock changes, what do Xt timers do, anyway?  If I have
-   a timer set for 30 seconds from now, and adjust the wall clock +15 seconds,

-/* Some crap for dealing with /proc/interrupts.
-
-   On Linux systems, it's possible to see the hardware interrupt count
-   associated with the keyboard.  We can therefore use that as another method
-   of detecting idleness.
-
-   Why is it a good idea to do this?  Because it lets us detect keyboard
-   activity that is not associated with X events.  For example, if the user
-   has switched to another virtual console, it's good for xscreensaver to not
-   be running graphics hacks on the (non-visible) X display.  The common
-   complaint that checking /proc/interrupts addresses is that the user is
-   playing Quake on a non-X console, and the GL hacks are perceptibly slowing
-   the game...
-
-   This is tricky for a number of reasons.
-
-     * First, we must be sure to only do this when running on an X server that
-       is on the local machine (because otherwise, we'd be reacting to the
-       wrong keyboard.)  The way we do this is by noting that the $DISPLAY is
-       pointing to display 0 on the local machine.  It *could* be that display
-       1 is also on the local machine (e.g., two X servers, each on a different
-       virtual-terminal) but it's also possible that screen 1 is an X terminal,
-       using this machine as the host.  So we can't take that chance.
-
-     * Second, one can only access these interrupt numbers in a completely
-       and utterly brain-damaged way.  You would think that one would use an
-       ioctl for this.  But no.  The ONLY way to get this information is to
-       open the pseudo-file /proc/interrupts AS A FILE, and read the numbers
-       out of it TEXTUALLY.  Because this is Unix, and all the world's a file,
-       and the only real data type is the short-line sequence of ASCII bytes.
-
-       Now it's all well and good that the /proc/interrupts pseudo-file
-       exists; that's a clever idea, and a useful API for things that are
-       already textually oriented, like shell scripts, and users doing
-       interactive debugging sessions.  But to make a *C PROGRAM* open a file
-       and parse the textual representation of integers out of it is just
-       insane.
-
-     * Third, you can't just hold the file open, and fseek() back to the
-       beginning to get updated data!  If you do that, the data never changes.
-       And I don't want to call open() every five seconds, because I don't want
-       to risk going to disk for any inodes.  It turns out that if you dup()
-       it early, then each copy gets fresh data, so we can get around that in
-       this way (but for how many releases, one might wonder?)
-
-     * Fourth, the format of the output of the /proc/interrupts file is
-       undocumented, and has changed several times already!  In Linux 2.0.33,
-       even on a multiprocessor machine, it looks like this:
-
-          0:  309453991   timer
-          1:    4771729   keyboard
-   
-       but in Linux 2.2 and 2.4 kernels with MP machines, it looks like this:
-
-                   CPU0       CPU1
-          0:    1671450    1672618    IO-APIC-edge  timer
-          1:      13037      13495    IO-APIC-edge  keyboard
-
-       and in Linux 2.6, it's gotten even goofier: now there are two lines
-       labelled "i8042".  One of them is the keyboard, and one of them is
-       the PS/2 mouse -- and of course, you can't tell them apart, except
-       by wiggling the mouse and noting which one changes:
-
-                   CPU0       CPU1
-          1:      32051      30864    IO-APIC-edge  i8042
-         12:     476577     479913    IO-APIC-edge  i8042
-
-       Joy!  So how are we expected to parse that?  Well, this code doesn't
-       parse it: it saves the first line with the string "keyboard" (or
-       "i8042") in it, and does a string-comparison to note when it has
-       changed.  If there are two "i8042" lines, we assume the first is
-       the keyboard and the second is the mouse (doesn't matter which is
-       which, really, as long as we don't compare them against each other.)
-
-   Thanks to Nat Friedman <nat@nat.org> for figuring out most of this crap.
-
-   Note that if you have a serial or USB mouse, or a USB keyboard, it won't
-   detect it.  That's because there's no way to tell the difference between a
-   serial mouse and a general serial port, and all USB devices look the same
-   from here.  It would be somewhat unfortunate to have the screensaver turn
-   off when the modem on COM1 burped, or when a USB disk was accessed.
