So to translate the new stuff we would actually have to stop the channel

that is composed of four ccws A,B,C,D and an execution of a channel
programs composed of ccws A,B immediately followed by and execution
of a channel program composed of the ccws C,D is not the same. I.e. it
is not generally safe to break a chain of ccws.
Exploiting suspending would have been my idea. Probably combined with a
new interface that fetches ccw-by-ccw.
But I don't think it makes sense to spend time thinking about this
right now.
IMHO exploiting suspending won't work, because the rsch starts a new
chain. If the suspend is a part of the original program the author
of it is responsible to make sure this ain't a problem. But if we
start setting the suspend flag ourselves, we may end up in trouble.
