If you need to run the functions concurrently, use threads. Else you
can setup a simple signal-handler for SIGALRM and set the time

import signal

def setup_signal():
  # Wait 5 seconds before alarming
  signal.signal(signal.SIGALRM, signal_handler)

def signal_handler(signum, frame):
  print "I got an alarm!"

  # need to resetup the signal

# A pointless loop
for x in xrange(500000000):
  if (x % 100000) == 0:
    print x
