I don't think using an allocator that "releases memory back to the OS as
much as possible" is a good idea for normal operation. Ideally one would
want to treat allocations for such operations differently e.g. by
dynamically changing the malloc() parameters (via mallopt()) so that the
memory can be freed after the operation is over. Unfortunately, other
malloc implementations (e.g. most BSD ones) don't allow you to change
the parameters dynamically. I'm not yet familiar enough with samba
internals to know if there's a better way :)
