You may want to import omalloc (based on mmap malloc, written from
scratch by Otto Moerbeek) with lots of security features:

http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/stdlib/malloc.c
http://www.openbsd.org/cgi-bin/man.cgi?query=malloc

It does assume that mmap() is randomised and NULs the result.
