Yes, you do need [super close] - that's probably what's making the
document controller not register your document having been closed.
The call to super's close is what will eventually deallocate your object.
If you are just using -close to release instance variables and close
file handles, the standard thing is to do that in -dealloc instead,
and not mess with -close, unless there's really something that has to
be done before the AppKit code knows that your document will be
closing (unlikely).
