recv is a generic method used by all objects deriving from NsObjects to
receive packet. recv is defined , actually its a place
holder in NsObject. It is really defined by the individual sub-classes.

so Connector objects have a variable target_ defined for
the object to which it hands down a packet to.so all pkts recv'd by the
object and having been processed is handed down to this target_.
Queue being a subclass of Connector inherits the variable.
