TooManyConcurrentRequests while committing on bound branch

[Martin Pool]

I had this error while comitting on a bound branch (using bzr+ssh)

Thanks,
Noam

I thought it was probably that, but I was surprised not to see some
kind of message about the connection being broken.

After a short discussion on #bzr, i found that this was caused because
during the bzr+ssh operation, ssh encountered a permission error on one of
the files, which in turn caused a disconnection, which in turn caused this
error (which does NOT describe a disconnection, obviously).

Noam.

I too did bump on this bug. Willing to send a bug I was presented this one which gave me a hint how to fix the problem.
Needless to say that a more suitable message would greatly help as bzr will not be able to fix that ! Too bad ;-)
