I think handling it with SIGALRM is a nice idea, granted that sigaction()
(POSIX-standardized) is used instead of signal() (quite dangerous due to
this very 'handler reinstalled' ambiguity).  Another way to do this could
be a window-list thread, but multithreading support just for the windowlist
is a bit of an overkill IMHO :)

Just see that somebody doesn't try to use/raise/ignore SIGALRM for some
other use in the future RP development :)

G'luck,
Peter
