Chas, you probably need to rebuild python with a bigger default thread 
stack size.  You have to code a bit to do it; it involves modifying the 
thread initialization code.  It isn't tough, I dont know if anyone has 
packaged up a patch for it.  You can check the zope-dev mail archives 
for details.
