(I'm going through old bug reports.)

I think using timers for the undo boundary is the right solution here --
Emacs will put a lot of stuff on the timer list, like
`blink-cursor-start' etc.  If this makes certain debugging difficult,
I'd suggest advising run-at-time to ignore the problematic timers or
something along those lines.

But Emacs is doing the right thing here, I think, so I'm closing this
bug report.
