:OK. In fact my problem was just a printf that allocated a buffer via
:__smakebuf at the very last moment (when all memory was allocated).
:This prevent free() to give back all previous pages up to this one. The
:problem was _not_ in malloc.c.

:Anyway, i learned a lot from hacking the source to catch the caller.
:Thanks.

Not to mention library routines which might malloc() something and
keep it around.
I find that the best way to allocate a large chunk of memory is to
use mmap( ... MAP_ANON ... ). That way you have complete control
over the memory. You need only page-align the request size
(getpagesize() helps there). You can then manage the memory with
madvise(), and free it completely with munmap().
