[using a static deleter]

Excellent! We now have a proof of concept that the modified specification
(that requires a complete type only on construction) has virtually no
overhead.

I like this scoped_ptr version because the modified shared_ptr in

http://groups.yahoo.com/group/boost/files/smart_ptr.zip

has the same requirement, i.e. a complete type is required only on
construction.
