The one problem with copy-on-write is that, if we implement it in software,
we end up paying the price to check it on every string write. (No free
depending on the hardware, alas)
Not that this should shoot down the idea of COW strings, but it is a cost
that needs considering. (I suppose we could have a COW subtype of the basic
scalar and string scalar)
