Hmmm... that's odd.  Can you show us how you're determining this?


Here's an example interactive session:

###################################################
>>> import threading
>>> def sayHelloOverAndOver():
...     while True:
...         print "hello"
...         time.sleep(10)
...
>>> import time
>>> t = threading.Thread(target=sayHelloOverAndOver)
>>> t.start()
hello
>>> hello
####################################################

Now every ten seconds, the word hello punctuates the prompt... and I can't
make it stop!  *grin*  Oh well.


Do you see the same kind of behavior on your end?  Good luck!
