...in the current version(s) of Classic Python, but not
necessarily in Jython, Python.NET, or (if my understanding
is correct) in some possible future version(s) of Python.
I wouldn't rely on __del__ necessarily getting called as
soon as the last reference goes away... try/finally is
more reliable and portable if you need _guaranteed_
