15213	Post WP3.1 PHP 5 register_shutdown_function() note - Remove Backwards compability	hakre		"In some classes (DB, Cache) register_shutdown_function() is used to mimic __destruct() in PHP 4 so it looks appropriate to remove that when wordpress codebase becomes PHP 5.2+.

But in fact the register_shutdown_function() probably must be kept for backwards compatibility, bećause __desctruct() is not called in PHP 5.2+ in all cases in which register_shutdown_function() registered functions are called.

So to remove the shutdown hook will break backwards compatibility because it is buggy for a mimic of __destruct().

I suggest to remove this buggy implementation and break with backwards compatibility."	defect (bug)	closed	normal		General	3.1	normal	wontfix	needs-patch
