Description:
------------
When using non-blocking sockets I get the following error:

Warning: stream_select(): unable to select [0]: No error in <b>c:\web\www\bot\bot\mod.eval.php(17).



Reproduce code:
---------------
Open stream to IRC server and after getting connection and identifying the script try to use the following code:

error_reporting(E_ALL);
echo (stream_select($gSOCKARRAY, $write=NULL, $except=NULL, 1, 1)===false);

Expected result:
----------------
I expect that for false there is no changes and for true there is some socket I have to test. 

Actual result:
--------------
All I get is the warning above. I tried to change timeouts but no luck at all. Still apache eats about 78% of my CPU.
