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).
