Use __del__ methods to improve gc?

[Edward K. Ream]

My app has unlimited undo.  As a result, most "user" data never truly gets
deleted: the undo stack keeps references to all such data alive "forever".

I am wondering whether it would be a good idea to put dummy __del__ methods
in the user data classes.  Would this help the gc by telling the gc what not
to look at?

Thanks,

Edward
