At the very least it would need to be configurable. On some 
machines (such as MacOS9 and earlier) the space is actually 
allocated, so by setting it to 2MB you would quickly run out of 

An even better option might be to let the Python program 
influence the thread stack size (thread.setstacksize(), maybe? 
An optional parameter to the thread start method? A more 
abstract hint not mentioning actual numbers but just 
small/normal/big?), after all it will know (to some extent) 
whether it wants many threads with small stacks or a few threads 
with big stacks.
