It looks like you forgot to send the signal. One way you could implement
this code is:

from signal import signal, SIGINT
from os import getpid, kill

def signalHandler (signum, frame):
    print 'signal handler called for signal %d' % (signum,)

signal (SIGINT, signalHandler)
kill (getpid (), 

Take a look at the manpage for signal(7) to get the list of signals you
can send to a process.

Hope this helps,
