22 RooSentinel is a special purpose singleton class that terminates
23 all other RooFit singleton services when the process exits.
24 
25 All function RooFit singleton services are created on the heap with
26 a static wrapper function to avoid the 'static initialization order fiasco'
27 but are not automatically destroyed at the end of the session. This class
28 installs an atexit() function that takes care of this
