[Bf-python] OT: *_dealloc functions

[Ken Hughes]

While playing around, I wondered what would happen if I didn't define a 
foo_dealloc() function for a new type and then called PyType_Ready.  As 
I expected, an entry was created in the tp_dealloc slot which I assume 
is the general Python object deallocation function.

So might I suggest we save a little space and not declare those local 
dealloc functions unless they're really needed (i.e., the object has its 
own allocated memory), as long as the type initialization is done with 
PyType_Ready?
