Comment 1 for bug 1103448

Thanks for the complete report.

The retry strategy is the easiest to use since that needs only a minor update
in the code while, as discussed on irc, the bzr+ssh one requires to use a
launchpad user with an authorized ssh key. Hence, I'll try first to use the
retry strategy.

If that doesn't work, we can go for the second options since we're going to use
a launchpad user account for tarmac in the future anyway.
