Simple Threading Example Doesn't Work (2.5.1)

[Seun Osewa]

Hello,

I've tried to run several threading examples in Python 2.5.1 (with
Stackless) For example:

import threading

theVar = 1

class MyThread ( threading.Threa d ):

def run ( self ):

global theVar
print 'This is thread ' + str ( theVar ) + ' speaking.'
print 'Hello and good bye.'
theVar = theVar + 1

for x in xrange ( 20 ):
MyThread().star t()

It doesn't work. It says there's an error in Queue.py in:
self.mutex=thre ading.Lock()
AttributeError: 'module' object has no attribute Lock

The funny thing is that when I use the -O switch, it seems to work.
I'm baffled by this. What do you think is happening?

Thanks.

Any chance that you have a module called `threading` that is not the one
in the standard library? Perhaps you named the script above `threading.py`! ?
