Sleep for 0 seconds to release GIL

[tbeamish-benchsci]

Description

time.sleep(0) in some cases to release the GIL and allow other threads to run.

Based on this article and this SO post, you can sleep for 0 seconds to release the GIL and allow other threads a turn. "Who goes next" is up to the scheduler.

This should yield faster responses overall. The processes will still consume 100% CPU (for their duration) but will be polite and let others have a turn.
