[PATCH v2 3/3] tests: Add free-without-remove test

[Derek Foreman]

From: Markus Ongyerth <wl at ongy.net>

[Derek Foreman <derekf at osg.samsung.com> moved this into resources-test]

---

I moved this behind Markus' back, so let's not go landing it if he's
not ok with that change.  I think it's a great illustration of the
problem and would like to see it land though.
