    _______________________________________________________

Details:

On allocation using mem_malloc(), the returned pointer (mem) is put MEMP_SIZE
after the original struct memp. However, since the 'next' pointer of struct
memp is not used while not in the pool, we can return the struct memp as mem,
resulting in not wasting the 4 bytes (for me, could be more or less :) used
for struct memp. Not much, but bit by bit...

See attached patch
