Issue 28873: test_unittest failures when refleak hunting (original) (raw)

test_unittest currently fails for me when hunting refleaks (Fedora 25):

$ ./python -m test -R 3:3 -v test_unittest

Ned, I'm not sure if this should be a release blocker or not.

Superficially, it looks like it's just a test bug arising from running the test multiple times in the same process, but I unfortunately don't have time to investigate further today.
