 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.
