Which IDLE? Which Python? Which Windows?

Works for me on Windows2000, Python 2.3.2, Idle 1.0


If I run a thousand threads IDLE uses over 64MB unless I add a little
delay in between spawning threads.  Using the Python interpreter, not
IDLE, I can add a time.sleep(.0000015) and get away with 10,000
threads piling up with output to print.  IDLE needs more time, try .01
sec and watch your Task Monitor.  (Though 100 threads isn't much of 
a load....)
