In (thinly) related news, we spent hours trying to track down the misbehavior
of the low memory global MemErr after a call to SetGrowZone. We had
in MacsBug, the instruction 'TST.W MemErr' listed. We'd do a 'dw MemErr' and
get an error code we'd never seen before and wasn't listed anywhere. After
single-stepping the TST, we'd do another 'dw MemErr' and it would turn
out to have CHANGED to 0. We finally decided that on the IIci, there
was something wrong with the MMU, because this behavior did not appear on
other machines. Anybody ever seen or heard of anything like this?
