Public bug reported:
I'm running tox -e py27 under Ubuntu 12.04 desktop 64 bit in a VM on my
laptop with 4 GB or RAM allocated. The memory in the run creeps up to
4GB and then near the end, it drops back down to about 2GB and in the
end, I get numerous tox failures, many indicating out of memory and too
many open files:
