Provision takes a long time (calling /handler_cleanup 100s of times) due to random SSH failures

This looks the same as the original error reported in issue 771236.

I think xixuan's fix for the excessive ssh requests can reasonably wait until she's back if we start managing the sshd configuration on our devservers via puppet.

phobbs and ayatane were working on that, but I've lost track of the current state.

A note, I think using the exact same config file on both Ubuntu and Goobuntu machines is reasonable.
