# The client writes 300 messages to Sys::Syslog native method.
# The syslogd writes it into a file and through a pipe.
# The syslogd passes it via TCP to the loghost.
# The server blocks the message on its TCP socket.
# The server waits until the client as written all messages.
# The server sends a SIGHUP to syslogd and reads messages from kernel.
# The client waits until the server has read the first message.
# Find the message in client, file, pipe, syslogd, server log.
# Check that the 300 messages are in syslogd and file log.
# Check that the dropped message is in server and file log.
