- I'd not pass selected signals to the child. The parent can still be
killed with a whole bunch of different signals that are not passed or
cannot be caught or the child process handle them gracefully.
Signals should be send to the PID from the pidfile anyway. If someone
is sending signals to the parent he has no right to expect well
behaviour from the parent.
- Now that we handle the pidfile fully in the parent, I'd move dropping
provileges after fork(2) and pidfile_write(3). This way pidfiles will
always be created with root privileges and we can forget about all the
mess with pid directories, etc.
- With the above you can wait for child to exit with simple wait(2).
