I don't know. I have no access to Python on Windows. Maybe there is
setitimer support on Windows. Or maybe you can use the threading.Timer
object, like this:

import signal, os
import threading

signalcode = signal.SIGALRM # on Windows, choose one that exists there.

class AlarmError(Exception):
    pass

def interrupt():
    os.kill(os.getpid(), signalcode)

def execute(command, timeout):
    threading.Timer(timeout, interrupt).start()
    try:
        exec(command)
    except AlarmError, e:
        print e
        print 'Aborted "%s"' % (command,)
    print "continue work"

print "The everlasting command"
execute("while 1: pass", 10)
print "The End"
