In commit v2.8.0~170 (ENH: Added ctest test options PROCESSORS and RUN_SERIAL, 2009-09-07) CTest learned to track the number of processors allocated to running tests in order to balance it against the desired level of parallelism. Extend this idea by introducing a new `PROCESSOR_AFFINITY` test property to ask that CTest run a test with the CPU affinity mask set. This will allow a set of tests that are running concurrently to use disjoint CPU resources.
