Ah, cool. Now that I see it again I remember why I didnt comment: its 
because it was complex and I didnt understand it.

I just spent a few minutes digesting the diagram, and yes, that gives a 
nice explanation of the top-level behavior.

I feel that the throttling mechanism is both important enough, timely 
(in that real users need it yet are stymied by it) complex enough, and 
interesting enough (ie it could merit a research paper) that we should 
dig back into it.

Add in coasters to the mix, and scheduling/throttling gets yet another 
dimension. (and both more complexity and an opportunity to reduce 
complexity based on knowledge of available workers).
