By the way - another issue with removing __del__ is that try/finally 
in generators (PEP 342) is implemented using it.

Which means that if you took away __del__ from the Python level, you 
could still simulate it by saving a reference to a running generator 
with a finally clause.  Of course, that would have at least as many 
problems as using __del__ directly, but there you go.  :)
