Comment 9 for bug 622011

I'm going to close the bzr side of this for the moment, unless it turns out there is something to do there.

At the moment qbzr starts multiple processes, and it's not easy for us to hold connections open across that. We could reinvent something like ssh connection sharing, and perhaps we should, but that seems a bit far from our core business. It seems to me a cleaner way to do this would be to have qbzr either reuse the same process for multiple operations, or for it to just do fewer bzr operations.
