I agree that a connection has reference semantics and that
connection::connected() therefore returns information about the thing being
referenced (as opposed to the handle itself).  According the logic above,
however, doesn't the fact that connection::block() is non-const seem
inconsistent?  In other words, it would seem that connection::disconnect()
and connection::block() should both be either const or non-const for
consistency.
