this afternoon i investigated running unit tests with virtual memory enabled,
with the expectation that they'll come from the I-Cache.
i discovered that I-Cache "priv-mode" is not hooked up in TestIssuer.
then, on trying to fix that, i discovered that the MSR is read one
cycle too late
i will fix that tomorrow, but it is quite intrusive - quite a big change to the
FSM. it's in the TODO notes of TestIssuer.
