It would be good if dprofpp simply issued a warning saying that its
timings are inaccurate, and pointing people towards Devel::NYTProf.

There are some things dprofpp can do that NYTProf doesn't (the -T
subroutine call trace for example). I've not looked to the other
profilers to see which support that well enough to recommend.


p.s. Meanwhile, if anyone wants it for NYTProf it would be fairly simple
to add. I'll happily assist anyone interested in working on it.
