It might also be desirable not to chain this functionality to --daemon, but
rather create a new option, such as --pidfile=FILENAME. Then you write to that
FILENAME if --pidfile is specified.
Also -- don't you need to remove the pidfile when mtt-relay exits? Note that
this should be done not only when mtt-relay exits normally, but also if
mtt-relay exits abnormally (e.g., ctrl-c or a local call to exit(), etc.).
