#!/usr/bin/env ruby

# Wait for a sender connection, send a correct hello, wait for a write
# request, then disconnect.  Simulate a server which crashes after
# receiving the write, and before it can send a reply.  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.
