What changes did you make to get this result?

IIUC the problem is with calling "malloc" before the dump and then
"free" that block after the dump, right?  If so, there's still some room
for improvement since Emacs could reuse a malloc'd area internally
(without going through free+malloc).

Can you show your current patch (I promise I won't make any comment
about style etc...).
