unable to select [4]: Interrupted system call

[Furgas]

When using automatic respawn a PHP warning is triggered in SimpleSocket.php:66, originating from WorkerPool.php:637:

socket_select(): unable to select [4]: Interrupted system call

Based on this answer from SO, I guess that pcntl_alarm is interferring with socket_select.

Thank you for your ticket. The issue should be fixed.

I guess it won't remove the warning. I will later try an approach with silencing operator on socket_select and use socket_last_error to check for this particular error (SOCKET_EINTR), and only then repeat the socket_select (clearing the error first, with socket_clear_error). I'm not yet sure what to do when the error is a different one - maybe manually trigger a warning with a message obtained from socket_strerror, to preserve the original behaviour.
