Daemon watcher process forked only in 1 clone.

Start in code

$singleProcess = new \Any\SingleDaemonWatcherProcess();
$forker = new \Mrden\Forker\Forker($singleProcess);
$forker->run();

Start via bin/forker

php bin/forker --process="\Any\SingleDaemonWatcherProcess"

Stop via bin/forker

php bin/forker --process="\Any\SingleDaemonWatcherProcess" --stop=1 will be stopped all (self and child process)

Stop via kill

kill PID - will be stopped all (self and child process)

Restart daemon watcher and all children processes vai bin/forker

php bin/forker --process="\Any\SingleDaemonWatcherProcess" --restart=1
