It might be 6 months from the time that we ship, but it's hasn't been 6 
months today and it hasn't been integrated into Fedora.  And there's no 
way that 6 months is enough time to let this stuff stabilize.  We're 
still finding bugs against the current python, let alone a new and 
relatively untested code base.

The memory management patch sounds nice, but I don't think we've done 
enough testing to know if the pain of upgrading and maintaining our own 
python code base (releases, bugfixing and security fixes) is worth the 
reported benefit of a patch.  Especially since we don't even know that 
we have a problem today.

I _certainly_ don't think that we're being lazy.  But I do think we're 
picking the battles that we want to fight.  And if you want to spend you 
time on that, I guess that's fine.  But I would rather you were spending 
your time on higher impact things, like making the wiki stuff work.
