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.

They've documented their upstream patches here: http://code.google.com/p/unladen-swallow/wiki/UpstreamPatches -- Philip Jenvey

Why won't you look at it? :) Actually, if these patches are to be merged someone should certainly look at them, and do the (possibly) remaining work. http://bugs.python.org/issue5683 http://bugs.python.org/issue5671 Thank you Antoine.
