Great work!

This could be some very important issue. I'd highly recommend looking
into it in some depth.

I'd ignore those. It's unlikely to be anything too structural.

Just generate the merges and splits like I told you initially. Store
64-bit vars into a merge of 2 original Value's.

I haven't looked at the patches, but have you fixed up the pipe caps
to disable the various features/etc that you don't implement when
