Comment(by rransom):

 Replying to [comment:2 Sebastian]:
 > It seems that you're trying to use signal newnym as a hack to work
 around an unrelated issue here. I'm not crazy about doing that, because it
 means we overload newnym with yet more functionality. Is there an actual
 linkability issue here without it?

 There is a minor linkability issue without clearing this state, but if I
 thought it could be exploited, I would have cleared it in my #3000-fix
 branch.

 But this state-purge is needed to keep SIGNAL NEWNYM from breaking Tor's
 functionality, so I don't see any reason to not do it on SIGNAL NEWNYM or
 to allow users to trigger it separately.  (Pounding on the HS directories
 more often is a bit rude, but less so than using SIGNAL NEWNYM repeatedly,
 or restarting one's Tor client as a workaround for this issue.)
