Description:
------------
When supplying a non-existent object reference as a callback, session_set_save_handler() hangs for a moment and php crashes, taking Apache with it.

5.0.3 win32 release, Apache1 SAPI, recommended ini, no external modules loaded. Also tested with 5.0.2, setup same as above.

Reproduce code:
---------------
<?php

class Foo {
	function Foo() {
		session_set_save_handler(
			array(&$arf, 'open'),
			array(&$arf, 'close'),
			array(&$arf, 'read'),
			array(&$arf, 'write'),
			array(&$arf, 'destroy'),
			array(&$arf, 'gc'));
	}
}

$foo =& new Foo();
echo 'bar!';
?>

Expected result:
----------------
The string "bar!" should be output.

Actual result:
--------------
No output, PHP crashes, taking Apache child with it.
