Because it isn't. I ran some tests when I added Boost.Move to it, and
copy-on-write is measurably faster than (emulated) move semantics, by
about the same amount that emulated move semantics are faster than not
having either. I'm hoping that compiler-supported move semantics will be
equal to copy-on-write, but until they're widely available,
copy-on-write is better.
