python timeout
You may use the signal package if you are running on UNIX:
import signal
# Register an handler for the timeout
def handler(signum, frame):
  print("Forever is over!")
       raise Exception("end of time")
   
# This function *may* run for an indetermined time...
def loop_forever():
     import time
     while 1:
         print("sec")
         time.sleep(1)
         
         
# Register the signal function handler
signal.signal(signal.SIGALRM, handler)
# Define a timeout for your function
signal.alarm(10)
0
try:
    loop_forever()
except Exception, exc:
    print(exc)
