I think we just never figure out the best way for a call to retrieve_node 
to indicate the retrieve was denied. write_node_post_locking was easy, 
because it already returned 0 or 1, so adding -1 wasn't hard. 
retrieve_node either returns a hash or undef, so what to return for 
declined isn't immediately obvious.

If someone can suggest what to return, then it's just a case of adding in 
the plugin return code checking, writing a test, and tweaking the 
documentation for retrieve_node :)
