Stepping through a multithreaded program

[Fernando Rodríguez]

Hi,

I was trying to step through a first attemp of multithreaded script (see
below), with PythonWin, but I'm gettign a very strange error:

---------------------------------------------------------------------------------
import threading

times = 100
delay = 10000

class egoistThread(threading.Thread):
def __init__(self, id, times, delay):
threading.Thread.__init__(self)
self.id = id
self.times = times
self.delay = delay
def run(self):
for i in xrange(self.times):
print self.id,
for j in xrange(self.delay):
pass

egoists = []
for elt in 'abc':
egoists.append(egoistThread(elt, times, delay))

"""
When I reach this point, I get a weird error see below
"""
for ego in egoists:
ego.start()


for ego in egoists:
ego.join()
------------------------------------------------------------------------------

The error is:
Traceback (most recent call last):
File
"C:\ARCHIV~1\python23\lib\site-packages\Pythonwin\pywin\framework\dbgcommands.py",
line 65, in OnStepOver

AssertionError: Can't stop the debugger pump if Im not pumping!

Any ideas? O
