Bug description:  STDIN won't allow nonblocking.

Description:
------------
STDIN won't allow nonblocking.

Reproduce code:
---------------
<?php

 stream_set_blocking(STDIN, FALSE);
 while (1) {
  echo 'infinate loop showing nonblocking problem'."\n";
  echo 'said:'.fgets(STDIN, 1024);
 }

?>

Expected result:
----------------
The test code should be a infinate loop with "infinate loop showing
nonblocking problem" said trillions of times fast like a infinate loop is
suposto do when you make a boo boo. instead it will say it once then wait
for input then wait again etc as a blocked resource is expected. but
"stream_set_blocking(STDIN, FALSE);" should be allowing it to do the loop
unblocked resulting in major screen flooding yet unblocking the resource
is ignored.

This means you can't do something like a client program in your shell that
is "interactive" like a Telnet client or similar.

I can dig the whole not reading as typing because that would be too "raw"
for common usage... [ie phrasing the backspaces etc though maybe a
seperate abaility? this would allow arrow key kinda stuff and similar...]
But waiting for a "\n" or whatever file ending shouldn't have any effect
on that loop. It should act just like a TCP or any other connection when
unblocked there the resource just has a return of no data.

"php -f test.php" I use to run it.

Actual result:
--------------
uses blocking when "stream_set_blocking(STDIN, FALSE);" was used.
