Somehow I expected that would be the answer :(

So, if I get, (say) three bytes processed, presumably I make another call for
just one.

Is it safe to cheat and without modifying the data block adjust the
byte count and increment the pointer passed to jack by the appropriate amount?

I'm thinking that I should only make two or three repeat attempts before
aborting.
