Not exactly what I was looking for, but probably a better solution to
my problem. I was already using both "ionice" and "nice", but without
any special parameters to either.
Specifying ionice class 3 (idle) and nice adjustment 19 (lowest
priority) appears to have had largely the desired effect.
Wish I had thought of that earlier...
