uprobes are being worked on (and that comes integrated with perf), and that will
give a good mechanism - and it (of course) wont be doing any context-switching.
Peter might be able to fill us in on the details of the review progress of the
uprobes patches.

It will hopefully be integrated into the perf ABI soon, so that developers and users
have a unified event platform for doing tracing, profiling, event logging and more -
all of which go back to a very similar looking event platform. (Not sure what's
holding up that process - there's no technical roadblocks really - it 'just has to
be done'.)
Thanks,
Ingo
