We're not adding loop instructions, it's just asking for trouble
since any user can attach BPF filters to a socket and it's just
way too easy to make a loop endless.

There's a reason no loop primitives were added to the original
BPF specification, perhaps you should take a look at what their
reasoning was.

It still applies now.
