I tried this on four different computers and was unable to duplicate
the problem.  I also asked Corinna to try it out and she was unable
to duplicate it either.

I assume that ssh-agent is disappearing after the first ssh connection
attempt.  Can you use "strace -ofoo -p <pid>" to attach to the ssh-agent
prior to the first ssh `hostname` and send the output here?
