Ugh. Definitely seems like a problem due to the lack of global variables
in SLICC. It isn't dependent on LRU, only that subsequent calls (in the
same wakeup) to cacheProbe() return the same thing. So any non-random
replacement policy would work.
I'll think about this and get back to you if I happen to come up with a
clean solution to using a random replacement policy.
