Comment:

 Thanks!

 I had a quick look through that commit. The code changes shouldn't change
 tor's behaviour. I wonder if the bug is in this commit, but the behaviour
 actually starts happening in the commit after it (a4fcdc5dec).

 In a4fcdc5dec, the following roles seem inconsistent:
 {{{
 +  CALLBACK(retry_dns, PERIODIC_EVENT_ROLE_ROUTER),
 +  CALLBACK(check_dns_honesty, PERIODIC_EVENT_ROLE_RELAY),
 }}}

 It's probably unrelated, but I don't think clients write stats:
 {{{
 +  CALLBACK(write_stats_file, PERIODIC_EVENT_ROLE_ALL),
 }}}
 (Do onion services write stats?)

 I'll do some testing over the next 2 days, and try to work out what's
 happening.
