I believe it's the wrong diagnosis :) If you look at http://bugs.python.org/issue3373 and the small script I posted, there are paths where the actual recursion level is still 1000.

It means each cPickle recursion level consumes more than 3KB of stack. It sounds awful enough to be considered a bug in cPickle, IMO. 2MB is plenty of stack space.
