Note that the post-mortem loop is terminated (if you do pdb.set_trace()
instead of pdb.pm(), that doesn't happen).
This is rather irritating then you're trying to post-mortem debug a
failed test with expensive setup, when leaving the postmortem pdb
session exits the process.
Python 3.1 is not affected. I don't have 2.7 handy.
