Comment:

 Some notes here:

 Clamping does not help us. It is specific to
 nsGlobalWindow::SetTimeoutOrInterval().

 DOMWorkers also have their own SetTimeout functions.

 There are several different DOM events, each with their own implementation
 of the timeStamp field. They do not share a common implementation.

 I think that if we're going to do it in the browser, we pretty much have
 to patch PR_Now(), or alter the code in about a couple dozen different
 places. It will be a big patch that is sure to generate conflicts...

 We'll also want to allow actual animations to have high-res timing (so
 they don't get jerky), but we'll need to specially handle the JS
 interface: https://developer.mozilla.org/en/DOM/event/AnimationEvent

 I think we need to stay in JS land for this one. I'm going to guess that
 in JS-land, this will take a couple of days to repeatedly experiment with
 and test.
