Unfortunately, the behavior occured just once after I last updated
Emacs to the new timer-based stuff, and I did not debug it then since
it just made me shrug and say "same bug as before".  So the frequency
of that occurence seemingly has dropped sharply, at least.  I am
rather sure, however, that I encountered it this one time after
recompiling Emacs.  If I manage to have it happen again, I'll sic the
debugger on it, something I should have done the first time.
