itimer

The itimer module adds support for sub-second alarm signal delivery on systems that support setitimer(2) and getitimer(2). Usage is very similar to sending alarm signals with the built-in signal module:

import itimer
import signal
import time

def handler(*args, **kwargs):
    print 'Alarm! (%s)' % time.time()

def main():
    signal.signal(signal.SIGALRM, handler)

    cont = True
    while cont:
        try:
            time.sleep(1)
            itimer.alarm(0.5)
        except KeyboardInterrupt:
            cont = False
    return 0

if __name__ == '__main__':
    exit(main())

(The example above will fire SIGALRM signals every 0.5s)
