Another work around is to do absolutely nothing in your main program
thread other than sit in:

while not_time_to_exit:

The main thread handles all signals.  Move the rest of your work
(including joining, etc) to other threads.  Have one of them set
not_time_to_exit and send a signal to yourself to cause the sleep to
exit.  (or instead of sleep, open a pipe and poke the pipe by writing
some data to it to indicate its time to exit vs loop again, etc.)
