But can we get the output from Elisp? `malloc-info' docstring says that
the output is done directly to srderr, which we cannot (?) access from
Elisp.

At least, it can indirectly demonstrate the impact of GC threshold onto
Emacs memory footprint. I guess it is what we worry about at the end.
Or does the fragmentation cause other severe effects in addition to
higher memory usage?
