I was under the impression, from the last time this was discussed on
emacs-devel, that the plan was to move to SYNC_INPUT after the Emacs
22.1 release.  If this is still the case, then I can go through the
Emacs sources to find and fix loops lacking QUIT.  Then we can make
the switch.

(On the other hand, it would be easier to do this after the unicode
merge.  I have several other cleanups that are also sitting around
waiting for the merge.)
