Its been hanging [or perhaps just /very slow/ in a regular expression
in pygments. I've also been seeing very slow performance in previously
fine code in oops-tools leading to very slow oops rendering. I don't
have enough data to say that these are/are not related yet. William
has been debugging this and may have more info.

I agree that its strange that this happened now. AFAIK, though, the
python re engine is self contained, not a thunk to a C re engine...
and Python hasn't been changed since we upgraded to lucid (octoberish
last year).
