This commit will have the parent process write the daemon PID before it exits. This ensures that immediately after parent exits a valid PID is available from the pid file.

I have an issue that I wish to
waiton the daemon PID so ask for the contents of the pid file immediately after the call to start the daemon. The problem is that there is a delay between the parent process exiting and the daemon writing it's actual PID to the pidfile. During this window the PID file exists but is empty so I can'twaiton the PID unless I have asleepimmediately after starting the daemon. This seemed like an clumsy solution so the proposed change would see the parent (which knows the daemon PID) write it out immediately before exiting.I hope you agree this is a sensible change. If not, perhaps you can think of a different solution.
