Well, drop official python2.4 support is potentially on the table. I
think it is reasonable to look at who needs new releases of bzr on
python2.4 and make sure it is worth the overhead to support it.

I'm intentionally CCing Martin <gz> because I believe he uses py2.4 on
Windows.

I personally don't see a big problem with bzr 2.2+ becoming python2.5+,
but I want to make sure to get feedback from our community about it first.
