Basically yes.  I'd like to be strongly typed unless we're specifically
dealing with data we want to manage off heap.  As such, I was thinking that
only record batches should be passed via the open ended bytebuf interface.

I see that you've made the other updates.  I'll merge those into the
execwork wip branch.

Thanks for all your effort.
