      // Some states used in the machine are special because they
      // perform actions while the machine is being terminated, actions
      // such as close files, call endRun, call endLumi etc ...  Each of these
      // states has two functions that perform these actions.  The functions
      // are almost identical.  The major difference is that one version
      // catches all exceptions and the other lets exceptions pass through.
      // The destructor catches them and the other function named "exit" lets
      // them pass through.  On a normal termination, boost will always call
      // "exit" and then the state destructor.  In our state classes, the
      // the destructors do nothing if the exit function already took
      // care of things.  Here's the interesting part.  When boost is
      // handling an exception the "exit" function is not called (a boost
      // feature).
      //
      // If an exception occurs while the boost machine is in control
      // (which usually means inside a process_event call), then
      // the boost state machine destroys its states and "terminates" itself.
      // This already done before we hit the catch blocks below. In this case
      // the call to terminateMachine below only destroys an already
      // terminated state machine.  Because exit is not called, the state destructors
      // handle cleaning up lumis, runs, and files.  The destructors swallow
      // all exceptions and only pass through the exceptions messages, which
      // are tacked onto the original exception below.
      //
      // If an exception occurs when the boost state machine is not
      // in control (outside the process_event functions), then boost
      // cannot destroy its own states.  The terminateMachine function
      // below takes care of that.  The flag "alreadyHandlingException"
      // is set true so that the state exit functions do nothing (and
      // cannot throw more exceptions while handling the first).  Then the
      // state destructors take care of this because exit did nothing.
      //
      // In both cases above, the EventProcessor::endOfLoop function is
      // not called because it can throw exceptions.
      //
      // One tricky aspect of the state machine is that things that can
      // throw should not be invoked by the state machine while another
      // exception is being handled.
      // Another tricky aspect is that it appears to be important to
      // terminate the state machine before invoking its destructor.
