`flyspell-region' is slow to the point that it is unusable.
Emacs -Q
M-x flyspell-buffer
This will visibly go through the buffer while checking it. It takes
about 6 seconds for the three lines, so it's impossible to use for any
reasonable document.
Now, repeat the above process but during spell-checking, move the
mouse around. --> Finishes in acceptable time.
Some debugging reveals that `accept-process-output' seems to be the
culprit. Commenting out the `with-local-quit' expression in `flyspell-
word' makes things go fast again. Giving it a `0` for the just-this-
one argument should prevent it from running timers, but that doesn't
help.
Given the mouse behavior, I think there's something seriously wrong
with the event loop or the process output handling in Nextstep.
