+ * imtcp --> tcpsrv --> netstrms (this sequence stored pPermPeers in netstrms class)
+ * then a callback (doOpenLstnSocks) into imtcp happens, which in turn calls
+ * into tcpsrv.create_tcp_socket(),
+ * which calls into netstrm.LstnInit(), which receives a pointer to netstrms obj
+ * which calls into the driver function LstnInit (again, netstrms obj passed)
