I was talking about this with Ted: he called the things to send and
receive "bunches" instead of slices which are larger. The idea would
be that the bunch has a list of cells (like a mark) and when one is
received, that has some of the same cells as we have, then the original
cells are not touched.

The big problem is making clones etc. work the right way: sometimes we
want clones to unify and sometimes not: for example, when we change the
definition of a clang routine in the root clone.
