Just curious. How much recursion are we talking about here???
Those CMS operations. 100 calls? 1000 calls?

If it's not near that, then the problem should be somewhere else.

Generally there should be no problems. The only case where the
stack size *may* matter AFAIK, may be threads. Because each thread
has its own stack --in non-stackless python-- stack size may be an issue
if it's too much and there are **many** threads. Otherwise, it should
not have any impact on performance.
