Why not have 3 settings? EntirePool, FailedConnectionOnly, AND UnusedConnectionsOnly What is the point of closing in-use connections since the connection would throw an exception on the next call anyway if it is bad? There is no added benefit to closing the in-use connection but there is a potential negative if for some reason the connection is still good.
