Why not a list of pre-made frames for each code block (default length 1)?

Or, IOW, per-code-block frame freelists (plural). Recursive generators have gotten quite popular in my code .

BTW, if a gazillion distinct functions run when starting up a large app, do we hang on to the memory for their gazillion distinct frames forever? Recycling from a common frame pool has memory benefits in cases other than just recursion. Experiment: run test.py from a Zope 2 or Zope 3 checkout, and look at highwater memory consumption with and without the patch.
