  Excellent thought.  As it turns out, if I boot a 4.99.73 GENERIC
rather than the GENERIC.MP I'd been running on, the same tests fail
running the same previously-built perl binary in pkgsrc/lang/perl5.

  So, a sparc64 problem that's not SMP related.  Perhaps there's
improper support for UltraSPARC I processors?

  Any suggestions as to what I could/should do to help track down a fix?
