Description:
------------
I write a script that is able to launch another process which runs in 100 seconds

The master process will check the child process in a loop to see if it is still running.

The child process is able to launch and run correctly. However, when I asign the resource returned by proc_get_status() to an array and return that array from a function, proc_get_status() does not work correctly any more. It caused the child process exit right after the first call.

Called in the same scope
========================
$process = proc_open('/usr/local/php5-fcgi/bin/php process1.php', $descriptors, $pipes);

// $process and proc_get_status() in same scope ==> OK
$status = proc_get_status($process); 

if (true === $status['running'])
{
  echo "Started process Id\n";
}
else
{
  echo "Unable to start a process\n";
}

Called from different scope and against a reference
===================================================

Return from a function
======================
return array(
        'pid' => $status['pid'],
        'handle' => $process
    );

Called against a reference
==========================

foreach ($running as $pid => $info)
{
   // first call will cause child process exit after that
   $status = proc_get_status($info['handle']); 
   sleep(1);
}

Test script:
---------------
You can read the sample code here: http://gist.github.com/403467

It contains 2 files: a master process named test3.php and a child process named process1.php

Expected result:
----------------
