I'd like to investigate this, but I can't reproduce it.  So far it only happens on the "AMD64 FreeBSD 9.0 3.x" buildbot.

Is there a way I can get remote access to that machine?

The build is --without-doc-strings. That should do the trick.

Good thinking!  I don't know when I can get to it though, maybe Sunday.

I think you just need to use the @requires_docstrings decorator for
the test. -- To me the failure looks expected if there aren't any
