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

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.
