[issue5315] signal handler never gets called

[Patrick Fink]

Patrick Fink <mail at pfink.de> added the comment:

A workaround to handle signals reliably that I successfully tested now is to execute everything within a subthread and let the main thread just join this subthread. Like:

signal.signal(MY_SIGNAL, signal_handler)
threading.Thread(target = my_main_function)
thread.start()
thread.join()

Doing it like this, the main thread should always listen to signals disregarding whether the subthread is stuck.
