       // 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.
