I don't like the approach. I would to just extend the existing daemon
(1) daemon2() returns a filter descriptor. It is the responsibility of
the child to write '\0' to this fd and close it, once it is done with
(2) If the child writes a code other than '\0', it is interpreted as
error by the parent and used as exit status.
(3) A new argument provides the default exit code in case the child
terminates before writing the status byte.
Whether a timeout should be provided as fourth argument is a question I
can't answer right now.
Note that the existing daemon functionality can be obtained by just
closing the descriptor returned by daemon2.
