/*! \file isc/pool.h
 * \brief An object pool is a mechanism for sharing a small pool of
 * fungible objects among a large number of objects that depend on them.
 *
 * This is useful, for example, when it causes performance problems for
 * large number of zones to share a single memory context or task object,
 * but it would create a different set of problems for them each to have an
 * independent task or memory context.
