Comment (by asn):

 Given that these machines are not offering too much protection and they
 were meant to be PoCs, perhaps the easiest fix here is to remove the
 `intro_acked` purpose from the accepted purposes list. This means that
 some times the machines are gonna terminate early, but that's fine since
 it's not like the extra padding is gonna fix circuit fingerprinting
 attacks.
