GnutellaRun lets Java's PeerToPeerAnwendung join peers on terminal-net.
The core's gnutella.ts does the same: a ping in Java's text format to
port 6346, a pong back, the ping sent on to the other peers and their
pongs back the way it came, at most the program's number of peers.
Departure from Java: a ping that comes a second time gets no pong and
its connection stays (Java's worker throws on the missing pong).
