pcntl SIGHUP Consumer restart not working in demo #489

Hi, Maybe I do something wrong, but after sending signal for restarting consumer using demo code (amqp_consumer_signals.php), the script stops catching other signals but restarts correctly, only

I'm not familiar with backstage code. So, do you know why this happens?

So problem here is that after SIGHUP new wait() loop is started inside signal handler function. It means new signal cannot be dispatched while previous handler function is not finished. Comment from docs: http://php.net/manual/en/function.pcntl-signal-dispatch.php#114234
