Queue is a double-linked list.

In nginx, memory allocations use pools, and in most cases you
cannot free individual allocations. The only options is to
destroy the whole pool.

For example, this naturally works with requests: all allocations
related to a request are done from the request pool, and are
automatically freed when the request is freed and its pool is
destroyed.

See here for more details about memory pools:
