Yes, disabling mixed priorities would prevent any higher-priority job
from starting while the catalog update was running.

What you may wish to request (I can't imagine it would be difficult) is a maximum mixed priority level option, where anything above that number ignores mixed priorities being allowed and waits till everything else is stopped. I would certainly vote for such a feature.

I will look into doing it myself, but I cannot guarantee anything, as my boss would first have to agree with our internal business need for such an additional feature, and I'm not sure we need it at the moment though I certianly see the appeal of the capability.
