 * @param min Allowed minimum number of available resources. Zero
 *            creates new resources only when needed.
 * @param smax Resources will be destroyed during reslist maintenance to
 *             meet this maximum restriction as they expire (reach their ttl).
 * @param hmax Absolute maximum limit on the number of total resources.
 * @param ttl If non-zero, sets the maximum amount of time in microseconds an
 *            unused resource is valid.  Any resource which has exceeded this
 *            time will be destroyed, either when encountered by
 *            apr_reslist_acquire() or during reslist maintenance.
 * @param con Constructor routine that is called to create a new resource.
 * @param de Destructor routine that is called to destroy an expired resource.
 * @param params Passed to constructor and deconstructor
 * @param pool The pool from which to create this resource list. Also the
 *             same pool that is passed to the constructor and destructor
 *             routines.
 * @remark If APR has been compiled without thread support, hmax will be
 *         automatically set to 1 and values of min and smax will be forced to
 *         1 for any non-zero value.
