[issue30727] [2.7] test_threading.ConditionTests.test_notify() hangs randomly on Python 2.7

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I still didn't see a code, but perhaps we could use a spin-lock. Every child thread increases the global counter, and the main thread waits until the counter equal to the number of child threads (sleeping for short time in a loop) before calling notify().
