create worker, work and die )

Hi, i need to create worker **inside other worker** and then correctly stop(destroy) it after it do some job.
something like that:
```
$small_worker = new Worker();
$small_worker->onWorkerStart = function() use (&$small_worker) {
echo "I've worked and that's enough.\n";
//$small_worker->stop(); //does not work (
//Worker::stop(); //does not work (
die(); // work, but i'm not sure if it's right
}
```
Thanks

No repository file, test, or entry point is named. Start by locating the Worker class and its onWorkerStart and stop lifecycle handling, then check the documented way to terminate a worker created inside another worker. Done means confirming a supported approach or clearly documenting the limitation, with a focused reproduction or test if the project supports one.
