OK.

Raw tracepoints are problematic as they require a per-tracepoint C
function signature to be synthesized by the tool (or hard-coded in the
tool or elsewhere). We haven't worked out how best do to this. OTOH,
markers don't require such hard-coding, so are simpler for a general
tool to interface to.

Thanks either way - I'm glad you found an existing tracing mechanism
usable and didn't choose/need to invent your own.
