    Not that simple. There's the risk of several processes writing
simultaneously to the same socket. It would mix and mess the messages.
You need the lock to synchronize writers. Plus the syslog daemon which
reads it expects a given format containing the log facility, the log
level, the application name, and properly made date/time format. This is
all wrapped in syslog().
