Hmm.  After checking in this patch, the gentoo x86 trunk buildbot
has a new failure in test_pickletools, with the following output:

test_pickletools

I'm having some difficulty figuring out how this could be
related to the checkin of this patch.

Anyone have any ideas where this might be coming from?
