Yep

I've tried again, running Emacs under X, and stopping it by typing C-z
at the debugger, rather than typing C-g at emacs.

This time I've gotten what looks like useful information:  by typing
"fin", and then hitting the return key a bunch of times, it became
clear that Emacs was doing a lot of garbage collection -- and a number
of the calls to mark_object took a good chunk of a second to finish
_apiece_.  And there are lots of such calls.

We can say that the universe consists of a substance, and this
substance we will call "atoms," or else we will call it
"monads."  Democritus called it atoms.  Leibniz called it
monads.  Fortunately, the two men never met, or there would have
been a very dull argument.
