Comment(by ClaudiusMaximus):
In the attached graph "i1.png", you can see that the sample times as
recorded in the .hp file are not uniform (they seem to measure "real time"
or "program time" instead of "non-profiling program time"). So I guess
the "removing overheads of profiling" property is indeed broken.
