- * block_signals: block all signals while handling this guest syscall
- *
- * Block all signals, and arrange that the signal mask is returned to
- * its correct value for the guest before we resume execution of guest code.
- * If this function returns non-zero, then the caller should immediately
- * return -TARGET_ERESTARTSYS to the main loop, which will take the pending
- * signal and restart execution of the syscall.
- * If block_signals() returns zero, then the caller can continue with
- * emulation of the system call knowing that no signals can be taken
- * (and therefore that no race conditions will result).
- * This should only be called once, because if it is called a second time
- * it will always return non-zero. (Think of it like a mutex that can't
- * be recursively locked.)
- * Signals will be unblocked again by process_pending_signals().
- *
- * Return value: non-zero if there was a pending signal, zero if not.
