 HSDir relays serve outdated descriptors now -- see the following line from
 [ticket:2401#comment:3]:

 {{{
 Jan 22 15:18:50.249 [info] rend_cache_store_v2_desc_as_client(): We
 already have this service descriptor gtvsxxxxxxxxxxxx.
 }}}

 The only way to prevent (non-malicious) HS directories from serving
 outdated descriptors is to make the set of relays with the HSDir flag
 stable.
