0068  * This test case performs the following actions:
0069  *
0070  * - Validate a set affinity error case with an unsupported subset.  This
0071  *   requires an affinity set with at least two processors.  On a system with
0072  *   exactly two processors, this is the set of all online processors and the
0073  *   unsupported subset is infeasible since the scheduler would select an
0074  *   affinity to all processors.  On systems with three or more processors,
0075  *   unsupported subsets are possible to construct.
