+# Problem: While any application (e.g. VMware) is holding the mouse and
+# keyboard grab, xscreensaver couldn't grab them, so it will ignore the
+# locking request. Without the keyboard grab, all input would still go
+# to the vmware window below the black screen, which is, you know, bad,
+# since you cannot enter your password to unlock the workstation again.
+
+# So we minimize vmware, lock the screen, and then restore vmware.
+# TODO: Add other virtualizers (vbox, kvm) later if needed.
