I've seen this too, sometimes via the virtinst test suite. Once upon a time I
tracked it down to whether the virtinst code did 'import selinux' or not, so
maybe it's a just some weird race, or a side effect of something other
libraries do in their cleanup path. By inspection alone the __del__ handler
doesn't seem to be doing anything wrong.
