Comment (by anonymous):

 I think there is a much better solution than those previously proposed.

 The object pool currently contains a single linked list of free objects,
 which makes it o(1) to allocate a single object.  Why not simply to have
 two linked lists -- one for freed objects and one for allocated objects?
 Then freeing all allocated objects becomes O(N) and freeing N objects
 manually is also O(N).
