Description:
------------
When using pcntl_alarm and the Fork driver - the blocked socket is interrupted - and the Fork Driver think's there's a socket error.
An update for the serviceRequest function attached

Reproduce code:
---------------
function serviceRequest()
{
while( true )
{
$readFDs = array( $this->clientFD[0] );

// block and wait for data
$ready = @socket_select($readFDs, $this->null, $this->null, null);

if ($ready === false && socket_last_error($this->clientFD[0])!==0)
{
$this->_sendDebugMessage("socket_select() failed.");
$this->shutdown();
}

if (in_array($this->clientFD[0], $readFDs) && (!$ready===false))
{
$data = $this->readFromSocket();

// empty data => connection was closed
if ($data === false)
{
$this->_sendDebugMessage("Connection closed by peer");
$this->closeConnection();
}
else
{
$this->_sendDebugMessage("Received ".trim($data)." from ".$this->_getDebugInfo());

if (method_exists($this->callbackObj, "onReceiveData")) {
$this->callbackObj->onReceiveData(0, $data);
}
}
}
}
}

Expected result:
----------------
Socket operation should continue unless socket_last_error indicates there was an error.

Actual result:
--------------
The client connection is terminated.
