can you please profile before and after? This could very well be to do
with the additional cost of shallowCopy for contexts, but it is inevitable
that a correct implementation is going to be more expensive than the simple
block-copy. The new implementation can be optimized, but we need to profile
first to be sure we're tilting at the relevant windmill.
