I did a little bit of testing. It appears that in the case of the double call to temp.compute(), temp.__del__ is never called. Apparently in CPython this happens if you have a reference cycle. I'm not quite sure what the source of the reference cycle is here (or why it only appears when calling compute twice), but that seems to be the likely culprit.
