Description:
------------
When attempting to use the read method with a specific size the method doesn't return unless at least that size is available, while in the documentation it is listed as being the *maximum* ammount of data to return, which appears to say that if less than that ammount is available, that will be returned instead.

Reproduce code:
---------------
[client]
$socket->send('echo');
$socket->receive(4096);
[server]
Sends back the send data (echo), which is less than 4096.

Expected result:
----------------
The 4 bytes of data available is returned.

Actual result:
--------------
No data is returned, and the socket blocks.
