Co-incidentally, I've just bumped into the fact that SSH does indeed, by
default, re-key after 1G to 4G, and glancing at paramiko it does it after 1G —
which is how much data is being reported by the activity logging in this case.

So, I'm pretty sure this is either a bug in paramiko, or Launchpad's Conch-based
SSH server (or both!), but not in bzr proper. The prime suspect would be
Launchpad I think, so I'm reassigning to LP guys to investigate. I'm leaving
this open against bzr though, because we should not be treating SSHException
like an internal error.
