[development] D6 Cleaning up on module uninstall

I have my module -install- working fine...creating the needed 
vocabulary, cck content type with fields, adding the content type to the 
vocabulary. Now I'm working on the uninstall, and the seemingly infinite 
cleanup that's needed, not that anyone would ever want to remove my 
module, once installed!

I believe I have the vocabulary and its data, and the cck content type 
and its data accounted for with:


   drupal_load('module', 'content');
   content_notify('uninstall', 'my_module');

and that brings me to nodes et al. There will be nodes (and node 
revisions) to be removed, and each node can have multiple field 
instances (cck image field). I don't seem to see a magic function that, 
given a node type, will remove all associated node data for that type. 
Also, I think I should remove the files that were uploaded as cck image 
content. Any tips on a good example of a complete "undo"? :)
