I'm not sure how to do that (and I don't have root on that machine,
so probably couldn't do it myself anyway).  Maybe I can arrange
something with the admins next week.

BTW, I am currently getting some interesting results from adjusting
SPINS_PER_DELAY in s_lock.c.  Will post results when I finish the
set of test runs.
