If I'm not mistaken, its not the 4BSD UNIX TCP/IP code that dumps the connection
when an ICMP host/network unreacahble arrives, but the application.  The
network code will deliver the appropriate error (EHOSTUNREACH or ENETUNREACH)
the next time the connection is referenced. Typically, the application sees
this "unexpected" error and bails out.
