Log Message:
Add __del__ callbacks. They are too useful to leave out.
XXX Remaining problems:
- The GC module doesn't know about these; I think it has its reasons
 to disallow calling __del__, but for now, __del__ on new-style
 objects is called when the GC module discards an object, for better
 or for worse.
- The code to call a __del__ handler is really ridiculously
 complicated, due to all the different debug #ifdefs. I've copied
 this from the similar code in classobject.c, so I'm pretty sure I
 did it right, but it's not pretty. :-(
- No tests yet.

 - Assignment to object.__dict__ is now possible, for objects that are
 instances of new-style classes that have a __dict__ (unless the base
