Not that I'd object to formatting this in better ways (especially
since a package to do that is already on ELPA), but from experience,
memory related problems are very rarely in GC-related areas.  So for
diagnosing memory leaks, the GC report is not very useful.  See, for
example, the currently on-going discussion on the bug list, where
someone with a 5GB RSS of the Emacs process posted the output of
garbage-collect, which shows fewer objects and less memory taken by
them than in my 13-day old Emacs session whose total VM size is just
0.5GB.
