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