Description:
------------
Under Windows XP and server 2003, proc_get_status returns a wrong PID.
While executing a system command I wanted to know its PID to be able to close it after a defined timeout

Reproduce code:
---------------
$cmd = "ping -t video-jobcoder";

$descriptorspec = array(
   0 => array("file", "stdin.txt", "a"),  // stdin is a pipe that the child will read from
   1 => array("file", "stdout.txt", "a"),  // stdout is a pipe that the child will write to
   2 => array("file", "stderr.txt", "a") // stderr is a file to write to
);

$process = proc_open($cmd, $descriptorspec, $pipes);
$pinfo = proc_get_status($process);
print_r($pinfo);


$timeout = 5;
while(@proc_get_status($process)){
	echo "$timeout..";
	sleep(1);
	$timeout--;
	if($timeout == 0) {
		echo "\r\nTimeout! Killing process with PID ".$pinfo[pid]."!";
		exec($path_to_pskill."pskill -t ".$pinfo[pid]." 2>nul", $res_pskill);
		for ($i=count($res_pskill)-3; $i<count($res_pskill); $i++) echo $res_pskill[$i]."\r\n";
		proc_terminate($process);
	}
}

Expected result:
----------------
$pinfo[pid] should contain the PID of the ping process
proc_terminate should close it

Actual result:
--------------
$pinfo[pid] returns a wrong number
