That's certainly odd. If it is still failing in the same way, with this branch, that means the connection is not being disconnected, despite the explicit call being made to disconnect() here. I don't have any good ideas for how else to fix this in tarmac. Digging through the bzrlib code, I did not see a way to force re-establishing the connection.
