Maximum number of threads

[Kirby Angell]

We are porting our applications from Python 2.2 on RH9 to Python 2.3 on 
RH9.  One of our apps used to be able to create threads with wild 
abandon, 800 or more if necessary.  With Python 2.3 we are hitting a 
hard limit of 254 on RH9 and around 400 on FC2.

What is the limiting factor for the number of threads we can create?  Is 
there a way to increase it?
