Very nice bug report, please, don't hesitate to file it on
launchpad. Anyway, failing to find a duplicate is not a deadly sin ;)

At worst, the community or the devs may finally realize it's a dupe but
could point to it if the report is clearer or better explain the
problem.

Even if the reason is not legitimate, it's still possible that we
shouldn't tracebak and create a new connection (I'm pretty sure we have
related and valid use cases that we fail to handle (and we raise
TooManyConcurrentRequests), http:/pad.lv/483661 for example. There is
also one use case I thought I reported but couldn't find anymore :-/

In fact, that's the opposite that is surprising: that we manage to resue
the same connection instead of creating a new "illegitimate" one. Trying
to use the same connection is "illegitimate", hence the exception. But
*why* we are doing this, is unclear.

This sounds interesting, would you mind share your setup (if only in
describing it a bit more) and tell us what is missing in the crontrib/
directory or if you used or modified something here ?
