test_bz2_bzcompdecomp test failures on py3.7
test_bz2_compdecomp tests are failing untranslated only on a memory leak from a
RPyOpaque_ThreadLock. I think that is converted to a
space.allocate_lock() call, but I tracked all the calls on the pypy code side (by adding a
space.allocate_lock() and adding a
__del__ method that prints) and did not find an allocate without a
delete. What else could be allocating a Lock?
