failover method have some bugs

[jiansongjay]

Stomp 1.0.0
Stomp.php
do
{
$read = fread($this->_socket, $rb);
if ($read === false)
{
$this->_reconnect();
return $this->readFrame();
}
$data .= $read;
if (strpos($data, "\x00") !== false)
{
$end = true;
$data = rtrim($data, "\n");
}
$len = strlen($data);
} while ($len < 2 || $end == false);

This code have something wrong. When I use failover and shut down one of mq instance. It will not come out from the code above. The $data will always be empty.
