I'd really like to hear what the programs are, and what the
performance difference is.

Because I'm surprised that the advantages of splice would really be
noticeable. I don't _dispute_ it, but I really would like this to be
actually _documented_, not just "Some executable-inspecting tools".

What tools (so that if it causes issues later, we have that
knowledge), and what are the performance numbers?
