Re: Bold by moving pixels problem

[Richard Stallman]

This patch makes it possible to GC inside a lot of places
that formerly could not.  A list of them is below.
I would expect that some of them don't GCPRO what they need to,
but I have not checked them for that.

It also looks like eval can in principle be called from a signal
handler.  We could solve that problem if we move all X event
processing outside of the signal handler, as someone suggested.  That
would mean that mouse highlighting doesn't update if you move the
mouse while a command is running, and the Emacs frame would not
rewrite itself if you move another window across it while a command is
running.  I think that would be a very noticeable step backwards.

Is there a way to get the job done by having the user
specify something other than Lisp code to run?
