parallel\Runtime::close

This is a simple test to show how close and kill works.
<?php
/**
 * Test close and kill
 * - main thread writes to main.log
 * - second thread writes to thread.log and shutdown.log
 * - main thread runs 10 seconds, second thread runs 20 seconds
 * - close will wait until second thread stops
 * - kill don't waits and kill immediately the second thread
