VERSION ==>                       #4.1.0

onExit(FUNC[, OPTS])->FUNC2()     #Like process.on('exit', FUNC) except also fired on exit signals,
                                  #providing those signals don't already have a listener.
                                  #Handler is FUNC(EXIT_CODE|null, 'SIGNAL'|null) instead of FUNC(EXIT_CODE)
                                  #FUNC can return true to abort exit, but only if exit was due to 'SIGNAL'
                                  #FUNC2() removes the listener
                                  #Noop in browsers
                                  #OPTS:
                                  #  - alwaysLast BOOL (def: false): fired after other 'exit' handlers, not among them
                                  #Issues:
                                  #  - patches process.emit|reallyExit() and uses a global EVENTLISTENER
