Microtask scheduling

[Kris Siegel]

This seems more like a platform-level feature versus something that needs
to be part of the ECMAScript standard. Also, keep in mind it's rarely a
good idea to explicitly call nextTick() in node as it executes the code
immediately after the current code is finished and before the next,
scheduled code (this can cause issues with processing I/O if you're doing
it too frequently).

In a browser you can sorta emulate similar behavior through IE's
setImmediate(), using postMessage() or even the requestAnimationFrame().
Granted none of those are exactly like nextTick() and I wouldn't mind
seeing something like setImmediate() become more of a standard but this
isn't for the ECMAScript group.
