Comment (by asn):

 Mike's fix LGTM too.

 Mike any chance we should also be checking for `HS_VANGUARD`
 `circ->purpose` in `connection_ap_expire_beginning()` too?

 WRT mike's question on comment:2: I don't think we have inherent rate-
 limiting for hsdir queries on hsv2 or hsv3, but I don't expect Tor clients
 to make many such circuits. Perhaps we should merge the bug fix patch we
 already have, and maybe open a separate ticket about investigating the
 potential issue of `count_pending_general_client_circuits()`?
