Standardize global `setTimeout`/etc.?

[Isiah Meadows]

Most runtimes (not necessarily engines) in my experience provide
either a synchronous `sleep` or the above `setTimeout`/etc. globals.
In addition, many popular testing frameworks (e.g. Mocha, Jasmine)
require them for important functionality. So here's my thought: it
might be a good idea to standardize these methods in the language
proper instead of just within the browser.
