Actually, "Hotshot" is the new profiler that was added in 2.2::
HotShot, a new profiler implemented using a C-based callback, has
been added. This substantially reduces the overhead of profiling,
but it is still quite preliminary. Support modules and
documentation will be added in upcoming releases (before 2.2 final).
