Call a function when a thread exits

[Giampaolo Rodola']

Hi,
I'm searching for a smooth way to call a certain function when a
thread has finished its job.
I guess I can keep calling isAlive() in a loop and call my function
when it returns False but it's not very elegant.
Actually I'm a bit surprised it doesn't exists an "atexit" function.
Something like:

import threading, time

def myfun():
time.sleep(1)
print "hello"

def cleanup():
print "thread finished, starting cleanup operations..."

t = threading.Thread(target=myfun)
t.atexit(target=cleanup)
t.start()


Is there a reason why there's no such thing in the threading module?

You can define your target function to clean up on exit. Using your
definitions of myfun and cleanup,

def mycleanfun():
try:
myfun()
finally:
cleanup()

t = threading.Thread(target=mycleanfun)
t.start()

Yes, I know. I was wondering if it could be a good idea proposing
something like an atexit() function to be included in threading
module.
