Could you use something like pthread_cond_timedwait, and wake the

That was my first thought too, then I read this in the man page:
ASYNC-SIGNAL SAFETY
The condition functions are not async-signal safe, and
should not be called from a signal handler. In particular,
calling pthread_cond_signal or pthread_cond_broadcast from a
signal handler may deadlock the calling thread.
So no, it's unlikely to work.
OK, how about using a separate thread to sigwait() on the desired
signal, and dispatch any work from the thread after the signal is
noticed.
