I have faith that some will.

But I'm also convinced that some high-profile sites will use it to do 
something expensive in a tight loop, they won't notice it's pegging their 
CPU because they're testing on a desktop, and then browser vendors will 
force a clamp of some sort to save CPU cycles.

And then we're back to setTimeout(..., 0).
