[darcs-users] gitit disabled for now

I'm wondering if the issues with gitit have to do with gitit calling darcs
changes and that hanging on the back end.

I noted darcs changes hangs, recently, here:

http://lists.osuosl.org/pipermail/darcs-users/2009-April/019313.html

What gitit (and patch-tag) really needs is better darcs changes performance,
I think, for history browsing.
