I was talking to BenWa today, and he asked how the RCU world handles
this situation:
1) DOM update starts at time t=0
2) DOM update finishes at time t=1, schedules 4ms setTimeout
3) Layout starts at time t=1
4) Timer fires at t=5, updates DOM
5) DOM update finishes at time t=6, schedules 4ms setTimeout
6) Timer fires at time t=10, updates DOM
7) Layout from item 3 finishes at time t=11.
It seems to me like in this case the RCU setup would basically skip
painting the t=5 frame, right?
We could make it delay the t=10 frame until the layout is done instead.
But we can't make it buffer up all the frames in hopes that the slow
layout is transient, afaict. Correct?
