execute() public static method

The loop MUST continue to run until it is either stopped explicitly, no referenced watchers exist anymore, or an exception is thrown that cannot be handled. Exceptions that cannot be handled are exceptions thrown from an error handler or exceptions that would be passed to an error handler but none exists to handle them.
