I'm going to take back my previous comment, turns out if you try to view the POST data in
firebug of an ajax call which is hanging (while loop or whatever), it'll screw it up, mess the
cookies up and do some weird stuff. Please delete this comment and my previous comment.

I seem to be experiencing this too, this is in my opinion CRITICAL.
In the class, it's supposed to die... picture something like this:
$someClass->someFunc(); //someFunc is supposed to die.
while (true) {
echo "Test";
sleep(5);
die();
}
It actually makes it to the while loop, doesn't print "test" though, it just stops
for 5 seconds. If I change to sleep(10), it stops for 10 seconds. No idea what is going on here.

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.
