Purpose:
    Use port hunting to test the Stream VFD
Description:
    The stream driver is tested by streaming data
    between two different processes on the local
    machine on a given default port.
    If this port is already is use, port hunting
    should find the next available port to use.
    The hostname/port information which is actually
    used by the sender is written to a temporary
    file which is then read by the receiver process
    to connect to the sender's port.

    For the purpose of testing I switched back
    the default port to use from 10007 to 5678
    which is at least already used by another
    service on modi4.
Platforms tested:
    x86 Linux, Irix 32/64 bit (modi4), Dec Alpha,
    Unicos on T3E, Hitachi SR8000, AIX on SP2
