It hasn't yet been extended to work with anything other than
UseParallelGC's eden allocation; but there are plans on the
cards to extend it to work with other collectors in the future
as well as making the collectors numa-aware. So, no, +UseNUMA will
not provide any current benefit with CMS/ParNew.
