And that's exactly the reason for this bug. :D

And note: fctnl() is called only when needed in the streams code.
(if stream is already blocked -> fcntl won't be called at all)

This works just fine for me without having 2 stream_set_blocking()
calls. Are you sure you're using PHP 5.2.2? And is that strace from
exactly that script you pasted here? And what was the configure line
used to configure PHP?

Description:
------------
When a stream has been obtained using stream_socket_accept from a
non-blocking server, php believes that it is itself non-blocking and
refuses to set it non blocking after a call to stream_set_blocking.
Reproduce code:
---------------
<?
$s = stream_socket_server("tcp://0.0.0.0:12345");
stream_set_blocking($s, false);
$c = stream_socket_accept($s);
// code will work if uncommented
//stream_set_blocking($c, true);
stream_set_blocking($c, false);
?>
Expected result:
----------------
Expected result is that $c is non-blocking, which it is *not* unless
the previous stream_set_blocking($c, true) is uncommented (this may
reset some internal cache ?)
Actual result:
--------------
reproduce code strace:
listen(3, 5) = 0
fcntl64(3, F_GETFL) = 0x2 (flags O_RDWR)
fcntl64(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
poll([{fd=3, events=POLLIN|POLLERR|POLLHUP, revents=POLLIN}], 1, 60000)
= 1
accept(3, {sa_family=AF_INET, sin_port=htons(58901),
sin_addr=inet_addr("127.0.0.1")}, [16]) = 4
[stream_set_blocking($c, false) does nothing here]
close(4) = 0
close(3) = 0
[script ends]
reproduce code strace with second call uncommented :
listen(3, 5) = 0
fcntl64(3, F_GETFL) = 0x2 (flags O_RDWR)
fcntl64(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
poll([{fd=3, events=POLLIN|POLLERR|POLLHUP, revents=POLLIN}], 1, 60000)
= 1
accept(3, {sa_family=AF_INET, sin_port=htons(58901),
sin_addr=inet_addr("127.0.0.1")}, [16]) = 4
fcntl64(4, F_GETFL) = 0x2 (flags O_RDWR)
fcntl64(4, F_SETFL, O_RDWR) = 0
fcntl64(4, F_GETFL) = 0x2 (flags O_RDWR)
fcntl64(4, F_SETFL, O_RDWR|O_NONBLOCK) = 0
[the two stream_set_blocking calls work here]
close(4) = 0
close(3) = 0
[script ends]
