Actually, the main thread always gets signals in Python:

"""
Any thread can perform an alarm(), getsignal(), or pause(); only the main 
thread can set a new signal handler, and the main thread will be the only 
one to receive signals (this is enforced by the Python signal module, even 
if the underlying thread implementation supports sending signals to 
individual threads).
