However, I was able to reproduce the crash even after removing the try/except, so I don't think this issue is related. Given that the crash only occurs at exit, I suspect this has something to do with finalizers running at a bad time during interpreter shutdown, but I don't have time at the moment to look into this deeply (I just spotted the GeneratorExit issue and wanted to check if that was the problem). I suspect this is an lxml or Cython bug, ultimately, but changing the test base class changes some ordering of events arbitrarily resulting in this heisencrash. Alternatively, it might have something to do with logging.
