[Boost-users] pool allocator based on element type instead of size?

I've found myself wanting something similar to 
boost::fast_pool_allocator, but with the following syntax for releasing 
memory:

using namespace boost;

std::list< T, fast_pool_allocator<T> > myList;

// Note that second template parameter is T, not sizeof(T).
// Basically I guess I just want a pool per type, even if
// two types have the same size.
singleton_pool< fast_pool_allocator_tag, T >::release_memory();

Is there a reason why this isn't doable that I should know about before 
I try to implement it?  Has something similar already been done (even if 
it's from outside the Boost community) so I don't reinvent the wheel?

Thanks,
Kenny Riddile
