Hello,
running the test suite on Debian I got this failure, only on python 3.3:

Thanks -- we've seen this on Travis CI as well. We need to get to the bottom of it.

Haven't seen this in a while -- I'm going to assume it has been fixed by other recent changes to make the parallelizing of tests less of an issue.
