Cool.  The only difference appears to be that git passes user at host, so the 
following:

$ export GIT_SSH=~/bin/fedora-git-ssh.sh
$ cat ~/.ssh/config
Host cvs.fedoraproject.org
ForwardX11 no
ForwardAgent no
ControlMaster auto
ControlPath ~/.ssh/controlsocket-%r@%h-%p

$ cat ~/bin/fedora-git-ssh.sh
#! /bin/bash

/usr/bin/test -e ~/.ssh/controlsocket-${1}-22 || /usr/bin/ssh -f -N ${1} 
</dev/null >/dev/null 2>/dev/null
 

exec /usr/bin/ssh "$@"

Seems to work.

Also turning off all forwardings seems to have helped as well.  ForwardX11 
triggers a call to xauth on each connection otherwise.  I have them turned on 
by default otherwise.

I wonder if this is worth shipping with fedpkg?
