[spec-reviews] Potential for coordination about task scheduling (#72)

The CSS Houdini effort is looking to specify a pipeline model for execution of script in layout/raster: https://docs.google.com/document/d/1Mw6qNw8UAEfW96CXaXRVYPPZjqQS3YdK7v57wFttAhs/edit?pli=1#

This (re)raises the question about ordering for delivery of other tasks in the platform (Mutation Observer change records, `Object.observe` records, `setTimeout` callbacks, `setIdleCallback` callbacks, `requestAnimationFrame` callback delivery). This has been discussed at some length, e.g., with @wycats at TC39.

The open question here is if the TAG should try to untangle this and generate a recommendation for scheduling in the non-layout/raster bits of frame generation.
