1# The client writes a message to Sys::Syslog native method.
2# The syslogd writes it into a file and through a pipe.
3# The syslogd passes it via TLS to the loghost.
4# The server receives the message on its TLS socket.
5# Find the message in client, file, pipe, syslogd, server log.
6# Check that a SIGHUP reconnects the TLS stream and closes the socket.
