Ingo, why are you arguing about static instrumentation when I don't submit any
static instrumentation in my patch ? You can argue about static VS dynamic
instrumentation all you want, but please don't apply this debate to a dicision
about including or not a core tracing infrastructure that has nothing to do
with the way instrumentation or probes are inserted.
