Hi servo-dev!
Servo exists to validate the idea that parallel browser architectures work.
Going parallel isn't always a good thing, and can sometimes be worse if there's
too much communication overhead. For example, in the current Servo design,
javascript is run in a different task than

Is it strictly enforced that the script task

Do such events always cause the layout task to require DOM access to create the
flow tree? If so, the layout task would still have to wait for the script task
to finish, meaning that layout still can’t occur unless forced by script.

It might happen if layout is flushed from outside the script task; window
resizing/device rotation being what immediately comes to mind, as today in
Servo those events go straight from compositor to layout without
I believe the answer today is nothing--i.e. it's a Servo bug. Clark's work
doubles as a nice way to fix it :)

Running this on Firefox takes 500 ns/iteration. Chrome takes 700 ns/iteration.
Servo before [1] lands took 8100 ns! That's paying a lot (some would say too
much) for a parallel architecture, when simple queries experience
