// standardHandling( ZMexception & x, bool willThrow )
// provides functionality common to many (most?) handlers:
//   record the handler's name
//   record (via x.wasThrown() ) the determined action
//   obtain permission, from the exception, to log;
//     if granted, invoke the exception's logger
//   return the determined action
