Description:
------------
If I have a COM object call into PHP (via com_event_sink or IE's
window.setTimeout) with a die() within the called code, then PHP hangs.
In the example below, IE comes up and waits around for 4 seconds, after
which an $ie->quit() is issued. In the event handler (function
OnQuit()) a die() is issued. While IE does shut down, PHP does not
return me the command prompt. This is from PHP CLI, of course.

Reproduce code:
---------------
<?php
class IESink {
public $terminated = false;
public function TitleChange($text) {
echo("title has changed: $text \n"); }
public function OnQuit() {
print "Quitting\n";
die();
print "Died\n";
$this->terminated = true;
} }
$ie = new COM("InternetExplorer.Application");
$ie->Visible = true;
$sink = new IESink;
com_event_sink($ie, $sink, "DWebBrowserEvents2");
$ie->Navigate("http://www.php.net/");
$start = time();
$quitted = false;
while (!$sink->terminated) {
com_message_pump(200);
if (time()-$start>4 && !$quitted) {
$quitted=true;
$ie->quit(); } }
print "Finished!\n";
?>
Expected result:
----------------
I expect to be shown the following three lines, ie to go away, AND for
PHP to terminate:
title has changed: PHP: Hypertext Preprocessor
title has changed: PHP: Hypertext Preprocessor
Quitting
Actual result:
--------------
The above 3 lines are shown, IE goes away, BUT php does not terminate.
Also, note that if I manually shut IE down, instead of waiting the 4
seconds, then I get the following additional line (and PHP still hangs
the cmd prompt):
Fatal error: Call to undefined method com::quit() in Unknown on line 0
It seems to me that the while loop stays active, since that's the only
place that $ie->quit() is issued.
