Description:
------------
stream_set_blocking seems to get ignored. There are no
errors or warnings, but the socket behaves as if it was set
to blocking.
The same code works as expected with php 5.0.1 on a FreeBsd
box, but not with 5.1.2 under gentoo linux. The piece of
code sample included is all that's needed to see the
problem.
Php is configured as stand-alone, not as an apache module.
Thanks a lot for any help you can provide!

Reproduce code:
---------------
<?php
set_time_limit (0); error_reporting (2047);
$sock = stream_socket_server("tcp://0.0.0.0:7000", $errno, $errstr);
stream_set_blocking($sock, 0);
$counter = 0;
if (!isset($sockCount)) {$sockCount = 0; }
while(true) {
$msgsock[$sockCount] = @stream_socket_accept($sock, 0);
if (is_resource($msgsock[$sockCount])) { $sockCount++; }
$counter = 0;
while($counter < $sockCount + 1) {
if (is_resource($msgsock[$counter])) {
echo "loop1:\n";
$buf = fread($msgsock[$counter],2048);
echo "loop2: $buf\n";
}
echo "keep looping: $buf\n";
if ($buf) { echo "buf: $buf\n"; }
$counter++;
}
}
fclose ($sock);
?>
Expected result:
----------------
It should echo "keep looping" if there is no input
Actual result:
--------------
It keeps echoing "keep looping" until a connection is made.
After input was received (made a telnet connection to port
7000 and sent some text thru), the trace stops at "loop1".
Only about every 30sec(or so) it does a complete loop. I think
that is after fread() times out intenally.
Also, if the connction is closed, it keeps looping thru "keep
looping" again.
