Upstream patch to fix issue #496. https://github.com/giampaolo/psutil/issues/496

Pulled from https://github.com/giampaolo/psutil/commit/f1275c19ac9e77b9169ca84dfb7d7701a8a2f9d7

Issue is fixed in psutil 2.2.0, but the module is pinned to >= 1.1.1, < 2.0.0

by OpenStack requirements.

Should psutil be updated to or past 2.2.0, this patch can be removed.
