For instance, let's say the author want the selector matching be accurate within 250ms, that leaves you 15 frames to accomplish the task. instead of optimising upfront you just queue all the possibly influenced elements in a list and you process them in a background thread asynchronously.

Processing in the background thread in parallel with DOM mutations 
involves figuring out whether the DOM mutations invalidate the results 
of your background processing, as you note.  Unless you're willing to 
just give up any guarantees of ever having this algorithm converge on 
the "right" rendering.
