More to the point, I don't think there is currently a simple way to prevent
a non-plan class app from going to a machine that also can get an app for a
specific plan class.  If you wanted to to that you would need to make a
plan class that excludes machines that fit the other plan classes.  But the
cpu_features list doesn't currently have a way of specifying a CPU without
a given feature.

We could add negative features to the CPU features, i.e. "-avx" would mean
"without avx", for example.
