Well, that's exactly what happens. Daft as it might seem, the __del__
method IS only called when an object is disposed of by the garbage
collector. CPython happens to use a refcounting garbage collector that
will usually dispose of things fairly promptly, but in the case of
cyclic references, that won't happen till the cycle detection GC goes
Check out the 'with' statement. Also, when you scorn something without
knowing your facts, you tend to make yourself look like a fool :)
