Review request for Plasma.


Summary
-------

We rely on runners to set their speed, however this may not be accurate on all systems. The programmer may even misjudge it. This patch introduces automatic rate limiting based on real performance. If a runner takes too long to return and it isn't a HighPriority runner, we pop it down to Slow. If, however, a slowed runner returns matches 3 times in a row with enough speed then we promote it to Normal.

Testing
-------

Ran with both fast runners that are slow, slow runners that are fast, and properly advertised runners. Speed was bumped (or not) appropriately.


Thanks,

Aaron
