Comment (by karsten):

 Hang on, arma's patch contains a bug:

 {{{
     rend_cache_clean(1000000);
     rend_cache_clean_v2_descs_as_dir(1000000);
 }}}

 That timestamp is 1970-01-12T14:46:40, and these two calls will only
 remove descriptors published three days *before* that timestamp.  arma's
 bug1944 branch contains one more zero, but 10000000 is still
 1970-04-26T18:46:40 and much too old.  A better number would be 2000000000
 which is 2033-05-18T05:33:20.  Or we can avoid timestamp maths and just
 use:

 {{{
     rend_cache_purge();
 }}}

 Similarly, I put in a call for
 `rend_client_purge_last_hid_serv_requests()` rather than the suggested
 `directory_clean_last_hid_serv_requests()`.

 Here's the full patch that I'm using now:
