Timers should be allowed in browser isolates

[yjbanov]

To reproduce:

import 'dart:async';
void main(args, sendPort) {
  Timer.run(() {});
}

This throws: "UnimplementedError: Timers on background isolates are not supported in the browser"

Since isolates compile down to web workers in the browser this functionality should be available.

More info: section "Features Available to Workers" at http://www.html5rocks.com/en/tutorials/workers/basics/

I'm guessing this is Dartium giving the error.

Correct, but you are bringing up a good point. It needs to work in both Dartium and in compiled JS.

#­4997 does spawnFunction. I only tried spawning from URI. That might be the difference.

Issue #14080 tracks a similar issue (for 'print').

This is fixed for 1.9. Isolate.spawnUri still creates a VM isolate in Dartium (i.e. not a WebWorker) but print and timers work, in a somewhat hacky way.
