Microtasks are clearly defined in the spec, is the idea, so we shouldn't 
have any issues in terms of where microtask checkpoints happen.

Basically there are two places they happen: when the JS stack completely 
unwinds and when the event loop spins.

There are important divergences.  If I do a dispatchEvent, there is a 
script entry point for each event listener that fires, but we don't 
really want to be resetting the slow script timer each time an event 
listener completes, I believe.  That's basically the setup we have right 
now and one I'd like to move away from.
