The git tree that Martin got from cvsps is much smaller that the git
tree I got from going to svn then to git.  I don't why the trees are
700KB different, it may be different amounts of packing, or one of the
conversion tools is losing something.

I am running cvsps-2.1-3.fc5 so I may be wasting my time. Error out is
535MB now.
He sent me some git patches, but none for cvsps.

I haven't come up with anything that is likely to result in Mozilla
switching over to git. Right now it takes three days to convert the
tree. The tree will have to be run in parallel for a while to convince
everyone to switch. I don't have a solution to keeping it in sync in
near real time (commits would still go to CVS). Most Mozilla
developers are interested but the infrastructure needs some help.

Martin has also brought up the problem with needing a partial clone so
that everyone doesn't have to bring down the entire repository. A
trunk checkout is 340MB and Martin's git tree is 2GB (mine 2.7GB).  A
kernel tree is only 680M.
