The Emacs dumper dispute

> This is factually incorrect: Emacs only uses its own malloc implementation during dumping. The dumped emacs executable uses the native malloc implementation on all the platforms mentioned in the previous post.

Really? Last time I tried to trace through the bugger it spotted the lack of malloc_set_state() and fell back to gmalloc for everything from dumping onwards, with fairly nasty consequences for memory usage. If the nasty consequences only relate to the relatively small amount of state stored during dumping, I'm fairly mystified as to how multi-hundred-MiB variances could be so apparent -- but Emacs is such a dynamic system that maybe I was being misled by perfectly normal run-to-run variability.
