I think in all cases where redisplay was really slow, it was either
due to slow Lisp being called by JIT font-lock, or by very long lines
in the buffer, or both. If we have several such windows, then yes,
having that run in parallel could speed up things, but is that really
a frequent case?
And anyway, working on several windows in parallel will have to deal
with the buffer-local stuff that changes global state, since each
window generally displays a different buffer, and the display code
makes that buffer current for the duration of time it works on a
window.
