#!/usr/bin/env ruby

# Wait for a sender connection, send a correct hello, then disconnect.
# Simulate a server which crashes after sending the hello.  We then
# reopen the server socket to check that the sender retries: since the
# command-line has gone away, and can't feed an error back to the
# user, we have to keep trying.
