Can this approach could be made "pluggable" in the sense of
interchangeable with the other type at the call site? Can you make a
version of these macros that adds reliable parameter passing? Can you
outline a proof-of-concept of the probe that would use these hooks?
Is live activation/deactivation of the probes a problem on complex
hosts (smp / preempt)?
