Reproducible under php-4.3.9
Smaller reproducible code
<?php
system("/bin/ps -l -p ".posix_getpid());
$fd = fsockopen("www.yahoo.com", 80, $errno, $errstr, 3);
system("/bin/ps -l -p ".posix_getpid());
if($fd) fclose($fd);
system("/bin/ps -l -p ".posix_getpid());
?>

Description:
------------
I see that fsockopen() causes a memory leak although of closing
filedescriptor.
Reproduce code:
---------------
system("/bin/ps -maxwvj -p ".posix_getpid());
$fd = fsockopen("www.yahoo.com", 80, $errno, $errstr, 3);
system("/bin/ps -maxwvj -p ".posix_getpid());
if($fd) {
$out = "GET / HTTP/1.1\nHost: www.yahoo.comConnection: Close\n\n";
fwrite($fd, $out);
$line = "";
while (!feof ($fd)) {
$lastline = fgets($fd);
$line .= $lastline;
if(ereg("Content-Type: text/html", $lastline)) { break; }
}
fclose($fd);
echo $line;
}
system("/bin/ps -maxwvj -p ".posix_getpid());
sleep(5);
Expected result:
----------------
You will see after issue fsockopen() memory usage rises, and if you
issue fclose() does not free memory.
