Comm::ConnectionPointer Ftp::Channel::listenConn

A temporary handle to the connection being listened on. Closing this will also close the waiting Data channel acceptor. If a data connection has already been accepted but is still waiting in the event queue the callback will still happen and needs to be handled (usually dropped).
