 I don't see it... but maybe it's early morning :P.

 We put the dir1/dir2 string in the service object and then we nullify
 their pointers so the tor_free() later will _not_ free their values
 leading to one single free within the service free?

 {{{
   service_1->directory = dir1;
   service_2->directory = dir2;
   /* The services own the directory pointers now */
   dir1 = dir2 = NULL;
 }}}

 What am I missing?
