Grmbl.. Ingo, can you zap all those WIP branches, please? They mostly
just get in the way of things. If you want to run them, merge them in a
private branch or something.

Yah, unfortunatly per-cpu variables live in the same namespace as normal
variables and so the above is incorrect, because the local @insn_buffer
variable shadows the global per-cpu symbol and very weird things will

This is of course consistent with C rules, where everything lives in the
same namespace...
