Should a priority request for the GIL take a priority number?

- If two threads make a priority requests for the GIL, the one with the 
higher priority should get the GIL first. 

- If a thread with a low priority make a priority request for the GIL, 
it should not be allowed to "preempt" (take the GIL away from) a 
higher-priority thread, in which case the priority request would be 
ignored. 

Related issue: Should Python threads have priorities? They are after all 
real OS threads.
