 That seems right.

 Sounds good. How about calling it BecomeDormantAfter ?

 I didn't check if it considered Hidden Services. I just took a look and I
 gathered that we can  check that rend_service_list == NULL, is there a
 better way to do it?

 Calling num_rend_services() is one way; I don't know if there's a better
 one.

 Okay; let's try to figure out what's going on here.

 (I tried to skip over issues where there were no questions; please let me
 know if I missed something important)
