We should ensure that there is at least one be that has enough 
non-isolated spus to accommodate all contexts of the affinity group, to 
avoid having a group that will never be completely scheduled.

The code uses the number of isolated spus in affinity_assert, but, since
isolated contexts come and go, we actually don't have guarantees. This 
is a design issue we have to care about. What would you suggest?
