New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>: test_socket creates a lock in the constructor of ThreadSafeCleanupTestCase. But since unittest creates an instance of test class for every test method, it creates around 400 locks. This exceeds the limit of 200 locks in NetBSD 8 and causes a failure.
