Ick. We're now less than 24 hours from the scheduled release date for 2.5
final. There seems to be a couple of approaches here:
1. Someone (it won't be me, I'm flat out with work and paperwriting today)
reviews the code and fixes it
2. We leave it for a 2.5.1. I'm expecting (based on the number of bugs found
and fixed during the release cycle) that we'll probably need a 2.5.1 in about
3. We delay the release until it's fixed.
I'm strongly leaning towards (2) at this point. (1) would probably require
another release candidate, while (3) would result in another release
candidate and massive amount of sobbing from a lot of people (including me).
