Ensure that threads only process one pump task.

Browse Source 
This is necessary because we will always deadlock if a thread takes on multiple pump tasks since pump tasks never return.

This means when using separate threads for certain systems (like physics or rendering), we need to be sure that there are enough threads to have at least one per system (to ensure forward progress).
