It might look like a worker-like process, but is actually pretty different:
it does not run continuously, for starters.

Yes, but we've clearly shown that this cannot work, because workers bring
in a model and APIs that can't work for us.

We have the same model than what the CSS and video folk need (something
happens on some thread, we run a bit of script on this thread). We also
need light input from ECMA so we don't redefine too much things. I think
it's the right way to do it to avoid wasting other people's time and have
solid spec and implementations.
