TooManyConcurrentRequests error on commit when ssh auth fail (bzr 2.0)

[blep]

I tried to commit using qbzr but forget to add my key in pageant and got the error below. I frequently forgot to had my ssh ppk on the first commit every day, and it is the first time I got such a error. The bug disappeared after adding my ssh key.

I'm running on Windows XP SP3 with Bazaar stand-alone install.
Notes: there is similar existing bugs, but there are all indicated as fixed in pre-2.0 release from what I've seen.

This was fixed in trunk, and part of the 2.1.0b2. I'm a bit hesistant to backport it to the 2.0.x branch because the patch is a touch large and 2.0.x is a stable branch... but it is a pretty straightforward change despite the line-count, so we can consider it.

Anyhow, this bug is a duplicate, so I'm marking it as such.
