[Boost-users] Using pool_alloc with std::map

I am using boost::pool_alloc with std::map like this:

typedef map<int, int, less<int>, pool_alloc<pair<int, int> > > MapT;
MapT myMap;

After myMap passes out of scope, I want to release unused memory from the pool.  
To do that, I need to get the type used to request chunks from the pool.  pair<int, 
int> is not the answer since map uses rebind to get a different allocator.  So how do 
I go about obtaining the correct singleton_pool interface?

Your help is appreciated.
