[RFC] Queue callbacks between render and componentDidUpdate functions.

[pvolok]

I'm experimenting with aphrodite in my current project. Aphrodite works well but has one flaw comparing to inline styles and css. It uses asap to inject styles in the next tick after render functions.

Like this:
Component.render()
Component.componentDidMount/componentDidUpdate()
injectCss()
browser's render

The problem with this is than we can't measure dom in componentDidUpdate as css-styles are not applied yet (unless they were injected after past renders). It would be cool if there was a way to still buffer styles in all render functions but flush them before componentDidUpdate.

This PR is just a guess how it might look like (I haven't dug into react src much). Not intended to be merged :)

I understand the problem in aphrodite but don't understand how this helps. Each component's componentDidMount/componentDidUpdate is called before the parent's componentDidMount/componentDidUpdate. ReactUpdates.asap is something completely unrelated to the asap project. There is no way to insert a callback after every HTML update before the component callbacks run.
