    // Some comments on exception handling related to the boost state machine:
    //
    // 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 which 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.
    // We've seen crashes which are not understood when that is not
    // done.  Maintainers of this code should be careful about this.
