Re: signalling errors in redisplay

[Richard Stallman]

    Maybe one can break out of that loop by letting Fsignal set a flag that
    the buffer in error shouldn't be redisplayed anymore, instead of evaling
    Lisp code withing redisplay in a condition-case.   But this might 
    render Emacs as unusable as in an infinite loop, depending on where the 
    error is signaled. 

That is a very good idea.  If that buffer is not redisplayed any more,
you can still save it and kill it.  And the rest of Emacs will still
work.  The disabling of redisplay in the buffer could last until
it is again modified--that way, you could easily try to resume normal
redisplay of the buffer if you want to try it.

Does anyone see a problem with this, or have a better idea?
