This doesn't answer your question but I've always questioned the use of the Resource Governor on jobs. You know the jobs are there and you know they're going to be used. It would be better to tune the code so the jobs don't use so many resources but still get the job done. This also means that there's less likelihood of something going wrong because the jobs won't be running as long.

There might also be some jobs where using the Resource Governor causes them to not run in the night hours allotted to them.
