Detailed Description

This is a small helper class used to manage closing a connection in the presence of transaction pooling. We can't actually close the connection until everyone using it is done, thus, we need reference counting.

User code should not use this class directly - it's used internally by the authors of DAAB providers to manage connections when using the DAAB methods.
