Description:
------------
stream_select blocks if there is still data in the read buffer which you haven't read yet..

Testscripts reads 8096 bytes (default chunksize) but there's already more to read. We expect stream_select to return $read again but it won't.

This works fine in 5.5.16 and previous versions.

Btw, tested using PHP5.5.16RC1 from http://downloads.php.net/jpauli/php-5.5.17RC1.tar.gz

Test script:
---------------
<?php

$host = 'tcp://php.net:443';
$chunkSize = 8192;

$fp = stream_socket_client($host, $errNumber, $errString, 5, STREAM_CLIENT_CONNECT);

stream_socket_enable_crypto($fp, true, STREAM_CRYPTO_METHOD_TLS_CLIENT);

$data = "GET / HTTP/1.1\r\nConnection: close\r\nHost: php.net\r\n\r\n";

fwrite($fp, $data);

while (!feof($fp))
{
	$read = array($fp);
	$except = $write = null;

	$changed = stream_select($read, $write, $except, 5, 0);

	if (!empty($read))
	{
		$read = fread($fp, $chunkSize);
		echo 'read ' . strlen($read) . PHP_EOL;
	}
}

Expected result:
----------------
read 8192
read 8192
read 8192
read 5961

Actual result:
--------------
read 8192
read 8192

and script hangs..
