I've been analyzing how much of the Python code is covered by the contributor agreements in the PSF's possession.

The logs show four mysterious IDs of the form uidNNNN; I'd like to figure out who two of those IDs were. (Two of the IDs are gone in 3.1-trunk, so I don't care about them.)

uid26747 has one commit that only affected Lib/test/test_generators.py. To me this reads like a Tim Peters commit message. Tim, does this seem familiar?

Added a non-recursive implementation of conjoin(), and a Knight's Tour solver. In conjunction, they easily found a tour of a 200x200 board: that's 200**2 == 40,000 levels of backtracking. Explicitly resumable generators allow that to be coded as easily as a recursive solver (easier, actually, because different levels can use level-customized algorithms without pain), but without blowing the stack. Indeed, I've never written an exhaustive Tour solver in any language before that can handle boards so large ("exhaustive" == guaranteed to find a solution if one exists, as opposed to probabilistic heuristic approaches; of course, the age of the universe may be a blip in the time needed!).

uid56795's commit is to Lib/idlelib/Debugger.py. Most of the commits to idlelib around this time are by Kurt Kaiser, but there are a few by Chui Tey. (In either case, both of them have signed agreements, so the code is likely covered.)

uid35364 cleaned up two bare except: clauses in Lib/mhlib.py and rfc822.py. No idea who this was -- IIRC, Skip did a lot of cleanup like this -- but the change is hardly the stuff of intellectual property litigation.

Clean up a bare except: clause.

uid28957's one commit is a regex tweak. The mention of an SF bug lets me identify this as probably by Sjoerd Mullender.

Fix for SF bug #425868. We should not depend on two spaces between words, so use the white space after the to-be-encoded word only as lookahead and don't actually consume it in the regular expression.
