With CnC, this is insufficient reasoning for test case 2, you have to
consider the prohibited reads stuff for test case 2.
In contrast, SC- (original email version plus about 10 more words) passes
all the tests that Bill has so far. In other words, if you are happy with
the guarantee that all SC executions past the discontinuity should have that
write, then you should choose SC- because it is much simpler. (And possibly
allows more optimizations.)
