As it stands the behaviour of [until] is correct, but it's a very dangerous
object unlike almost every other Pd object it's the only one beginners can
really screw up with.
An object can tell if it has a connection made to any of its inlets, so
perhaps the safety catch for [until] is not to work unless the condition inlet
is connected? If the condition is never satisfied due to user programming error
that's another thing but a first line of defence would be helpful.
