> Adds the ability to yield the procedure every execution step.
> by default, a procedure will try to go begin to end without stopping.
> This allows procedures to be nice to other procedures.
> one usage example is ServerShutdownHandler where we want everyone to make some progress.
> Allows procedure to throw InterruptedException, the default handling will be:
> "ask the master if there is an abort of stop. If there is, stop executions and exit.
Else, clear the IE and carryon executing. the interruted procedure will retry".
> If the procedure implementor wants a different behavior, the IE can be catched and custom
handling can be performed.
