Looks like the right place to start.  Like I said, figuring out
which language should get the interrupt and how to propagate the
interrupt across language boundaries will probably be trickier than
figuring out where to set the flags.

Yeah....  Emacs 21.1 is going into feature freeze soon, so it's a good
time for me to stop putting changes into it and focus on merging it
back into my guile-emacs source base.  Then when the final release
comes, I should be able to make diffs available rather quickly.
