git-svn dcommit problem with subversion mirror

Sorry if this has already been discussed.  I did not see it when I searched the
archive.  I love git and started using the git-svn bridge at work.  I found that
dcommit would sometimes stop abrubtly when dcommiting with a strange error
message; sorry, I didn't save the message, but I believe the problem was cloning
the svn mirror instead of the main svn repo.

I realized I was git-svn clone'ing our svn mirror instead of the main 
repository.  Our mirror is setup so that commits have to go back to the main
repo and then propogate back to the mirror, so sometimes the commit you just
made to the mirror isn't immediately available.  I think that tripped up
git-svn.  It might be helpful in the short term to make a note of that somewhere
when discussing git-svn.

Also, I realize that with Git it doesn't make sense to use the mirror since
there will be less interaction with the main repo.

I love the "Pro Git" book!  Great work.
