But if you have set MaxWallDurationPerJob in a QOS, the value set in the
association will be ignored, because the QOS have higher priority than
associations, as described on the page Ole mentions above.

This makes it slightly difficulty to impose per-user restrictions.  Our
current approach to, say, preventing a user from starting any more jobs
is to remove all the partition QOS from the user association.  This is a
little clunky, so I suspect there may be a more elegant way.
