Note that sleep() is entirely inappropriate for GUI applications, which should instead set a routine to resume processing
(that would be timer_cb below), activate a timer (set RUN to true), and relinquish control to the event loop. Another
excellent way to perform extended processing without making an application unresponsive is via an IDLE_ACTION, provided
that also regularly relinquishes control to the event loop, and can pick up where it left off when next invoked.
