That's worth quite a bit actually, I haven't been able to get it to pass
'make check' after implementing Greg's suggestions. It fails one of the
tests in lock_tests.py. How do you guys generally run an individual
test or test program? It's implied in the documentation that the test
programs support it, but does 'make check' have any options?
