[boost] [pool] Problem with ordered_malloc() and ordered_free()

I have a problem with ordered_malloc() and ordered_free() which might be 
from misunderstanding the documentation. I use these two functions to 
overload operator new[] and operator delete[]:

template <class T>
class mem_manager
{
protected:
 static boost::pool<my_allocator> mem_pool;

public:
 void *operator new[](std::size_t size) { return 
mem_pool.ordered_malloc(size / sizeof(T)); }
 void operator delete[](void *p) { mem_pool.ordered_free(p); }
};

I overloaded new and delete with malloc() and free() which works fine. 
However from what I understand I can't use them for new[] and delete[] - 
that's why I tried ordered_malloc() and ordered_free(). I haven't really 
investigated the problem yet because I'm not sure if I implemented these two 
operators correctly or if I understood ordered_malloc() and ordered_free() 
wrong. The documentation at 
http://www.boost.org/libs/pool/doc/interfaces/pool.html says something about 
merging free lists and preserving order with ordered_malloc(). Is this 
related to allocating an array? Or how shall I implement new[] and delete[] 
correctly?
