=head2 $self->daemon_fork()

Performs the first part of daemon initialisation.  Specifically,
forking.  STDERR, etc are still connected to a terminal.

=cut

sub daemon_fork {
    require POSIX;
    fork && exit;
}

=head2 $self->daemon_detach( )

Performs the second part of daemon initialisation.  Specifically,
disassociates from the terminal.

However, this does B<not> change the current working directory to "/",
as normal daemons do.  It also does not close all open file
descriptors (except STDIN, STDOUT and STDERR, which are re-opened from
F</dev/null>).
