Wouldn't such "massive overhead" likely affect the behavior of your
application (at least if you have any asynchronicity / concurrency),
making the value of the output questionable, or at least difficult to
interpret? One of the really nice things about Sharks CPU samplers is
the very low overhead - and therefore impact - while gathering
performance data.
