Yep.  What about the following:

   - int scm_create_new_os_signal (void)

   Return an integer that can be used as the signal number with
   scm_sigaction and scm_queue_os_signal.

   - void scm_queue_os_signal (int signum)

   Notify Guile that the OS signal signum has occured.  Guile will run
   the signal handler for it at the next safe point, as prepared by
   scm_sigaction.

   SIGNUM can be a number from signals.h, like SIGINT, or it can be a
   number returned by scm_create_new_os_signal.

   The function scm_queue_os_signal is save to be called at any time,
   including from OS signal handlers.
