[Python-Dev] Unladen cPickle speedups in 2.7 & 3.1

[skip at pobox.com]

How much of the Unladen Swallow cPickle speedups have been incorporated into
2.7 & 3.1?  I'm working on trying to develop patches for 2.4 and 2.6 (the
two versions I currently care about at work - we will skip 2.5 entirely).
It appears some of their speedups may have already been merged to trunk, but
I'm not sure how much.  If a patch to merge this to 2.7 is already under
consideration I won't look at it, but I interpreted Collin Winter's response
to my query on the u-s mailing list that not everything has been done yet.

Thx,
