`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.
