Bug description:  processes opened with proc_open may freeze on fatal error

Description:
------------
If the proc_open was inside a class object,
then on a fatal error the child process
is not killed. (Both CLI and Apache.)

That behaviour makes it difficult to develop
scripts based on classes using proc_open.

If the $proc is not inside a class object,
I obtained a similar freezing doing $proc = 0
before the fatal error.


Reproduce code:
---------------
<?php
class my_class
{
   var $proc, $pipes;   
   function my_class() {
      $this->proc = proc_open("cat -",
         array(
            0 => array("pipe", "r"),
            1 => array("file", "/dev/null", "w"),
            2 => array("file", "/dev/null", "w")),
         $this->pipes); 
   }
}

$p = new my_class();
printf("%s proc hangs on fatal PHP error?\n",
   is_resource($p->proc) ? "Open" : "Not open");
non_existing_function("hangs if open");
// not reached...
?>
