I would have to look at this one.  Maybe.. maybe not.  See below for
an explanation of what can happen on psim.

I will try to build this and look into it.  Ping me Wed if I don't post
back.

sp32 is particularly sensitive to the amount of work that can be done
between clock ticks.  On psim the period between clock ticks is measured
in number of instructions, so TICKS_PER_MICROSECOND == the number of 
instructions we treat as a microsecond.  So it could easily be too low 
for this test.
