Quick question out of ignorance: shouldn't the API offer an explicit
close method?  The reason is that in python, doing 'del foo' doesn't
ensure real deletion of the underlying object that  will fire the
close methods, since you may easily have other names pointing to the
same object.  Having an explicit, guaranteed way to call .close()
sounds  like a good thing to me, but I may well be missing something.
