Comment (by edupuis):

 1. Method boost::pool::purge_memory() does not require the pool to be
 ordered. Documentation has to be amended.

 2. Current implementation of boost::pool::release_memory() fails if the
 pool is not ordered. It could be implemented by adding a pool.order()
 function which could be called by the user to make an unordered pool
 ordered. The pool.order() function could also be called automatically if
 the pool maintains a boolean describing whether it is ordered or not.

 3. We could provide a gateway to release_memory() and to purge_memory(),
 the latter calling destructors of objects allocated, exactly what is
 already implemented in the destructor of object_pool.

 4. This is related to ticket #3789. In the current implementation,
 boost::object_pool can not be used to allocate arrays of objects.

 5. If ticket #3789 is resolved, this is probably not as needed. However,
 it could let a user choose between a slow 'object_pool::free()' or a slow
 'object_pool::~object_pool()' as described in ticket #3789, although I
 fail to see relevant usages where one would choose a slow free. The
 suggested template parameter seems useless for boost::pool as the caller
 chooses between the ordered or unordered malloc/free functions.


 Any comments ?
