You have done it correctly.  Looking at your code, I don't see much
you can do to improvie things with just sub-classing MenuProvider.

One thing you can do is subclass nautilus.InfoProvider and use the
update_file_info (or in the case of git master,
update_file_info_async) to collect file information asynchronously
when the directory is loaded, and then when the user right-clicks on
the file and get_file_items() is called, the information is already
there.  That may add more complexity than you want to deal with though
(for maybe not much benefit).
