Comment(by nickm):

 Okay, I just refactored the living heck out of rend_service_load_keys,
 because having two separate cleanup codas (one inside the loop and one
 outside) was making me super twitchy.  Now branch "bug2385" in my public
 repository (based on yours) could use some review, when you have time.
