When Internet is not available socket_connect throws a 'Host name lookup failure' PHP error

In no Internet available condition, the socket_connect call in Socket.php createConnection function throws the following error:

> A PHP Error was encountered
> Servetity: Warning
>
> Message: socket_connect(): Host loockup failed [-10002]: Host name lookup failure
> Filename: Adapter/Socket.php
>
> Line Number: 32
>
> Backtrace:
> [...]

that ignoring the possible false return, and any exception throwing and try&catch.

Is there any way to avoid that error message in that specific call?

Start in Adapter/Socket.php at the createConnection function and the socket_connect call around line 32. Trace how a failed connection is handled when Internet access is unavailable; done means the expected connection failure is handled without emitting the PHP warning shown in the issue.
