Hmm, interesting, I can try and see if I can reproduce it on more systems.

So the machine I was building on is an IBM x3650 with 2 quad core 2.5GHz
xeons.  Kernel is amd64, userspace is i386 wheezy, chroot is i386 jessie
buildd variant.

So I just tried some more tests.

jessie-amd64 on sid-amd64: works
jessie-i386 on sid-amd64: works
jessie-i386 on wheezy-i386(with amd64 kernel): fails
Same chroot copied to a sid machine (so 3.16 kernel instead of 3.2 kernel: works

It would appear that pytest fails on python 3.4.2 when the underlying
kernel is 3.2 for some reason that I can't even imagine what is.

I will try upgrading the kernel on our build machine to the
wheezy-backprot of 3.16 and see if that solves the problem and report
back.
