test_signal_receiver

#!/usr/bin/env python3
"""
The following scripts, this one included, are used together to debug the signal delivery system:

    o test_signal_delivery
    o test_signal_receive
    o test_signal_send

They are useful because they do not try to catch exceptions and therefore will show any errors
messages. To use, on three different terminals:

    1. start test_signal_delivery (never stops).
    2. start test_signal_receive (also never stops, but loops doing some work then sleeping
       for 5 seconds).
    3. Use test_signal_send when test_signal_receive is sleeping. When test_signal_receive
       wakes up, it should print "Interrup" before continuing its' work. It ignores interrupts
       while working.


To cleanup, kill -9 test_signal_delivery and test_signal_receive.
