Are there any buildbots that configure --with-pydebug? This could be a
debug-only issue.

That said, though, I just did a build without -j2 (on Linux - Debian
Wheezy amd64) and it worked fine. Doing another one with -j2 didn't
show up any errors either, but if it is a -j problem, then as Zachary
says, it could be a race.

What commit hash were you building from? It might have been broken and
then fixed shortly, and you got into that tiny window.
