 There is something wrong with how circuit_expire_building() applies
 timeouts to hidden services. There's some rather funky switch statements
 in there that grant hidden services a pass from timeout at certain stages
 in their handshaking, but not others. However, the end result seems to be
 that hidden service timeouts are actually *more* common than they should
 be for some reason. See my comments in #7157 for slightly more detail
 (though not much).
