If I remember correctly, alloc.c was added because malloc() has too
high overhead per allocation (and we create like millions of them). As
long as you keep allocation overhead low, it should be ok. Note that
we allocate a lot more than the mem-pool's main target (cache entries
if I remember correctly). We may have a couple thousands cache
entries. We already deal with a couple million of struct object.
