WHY does __sleep() need to be a destructor?

__sleep() is a function to control how an object is serialized, and the
object, as you seem to know, still exists, so no destructor should
happen at this point, in fact, if you look at it, __sleep() has not
expected to have any effect on the current object, its purpose is to
make sure that __wakeup() will get all the data it needs, and allow the
removal of data that it won't need.
