You calling it from the base so cleaning you be easier than looking for object referenced variables and setting them to null. Working in a large class hierarchy it could get painful.
__destruct()
and as far as object references in variables are concerned: the engine destructs all instance member variables when an object is destructed, so the reference counts of the referenced objects are already deceremented no need to free them by hand (this is even true for PHP 4)
you only have to take care of cleanup yourself when you have circular refence graphs ...
