Another step in the chain. Pipe the throttle update to the appropriate PollServiceTextureEventArgs. Each poll service having it's own throttle member is more consistent with the model then the region module keeping track of all of them globally and better for locking too. The Poll Services object is not set static to handle multiple nearby regions on the same simulator.

Next step is hooking it up to HasEvents
