Indeed.  Just as is the case with macros and preprocessors.  If/when
this problems turns out to be significant, we'll see if there's
something we can try to do, but for now, this seems like a fairly
remote problem.

I'm not sure.  Maybe it will depend.  I'm leaning towards having
a "main" major mode and leaving `major-mode' pointing to that.
As mentioned elsewhere, it might also be a better choice to let this
main major mode control the keymap.
