Not to worry. I think my code is flawed, needs to redesign
somewhere... with bin-packing, you have one thing to take out at the
same time as one thing to put in, it's obvious to do the taking-out
before the putting-in! but there's problems in my design making it
difficult to perform operations in that order.

Cheers,
James.
