The `time.sleep()` call should happen before the GC to give the worker threads time to clean-up their remaining references to objs. Additionally, use `support.gc_collect()` instead of `gc.collect()` just in case the extra GC calls matter.

I'm reasonably confident about this fix now. I was able to reliably trigger the test failure quickly by running it in a loop with multiple tests runners on the same CPU. I'm now able to run that loop for a long time without failures. |
