This is not entirely true, as we now also expect in our freeze_freeze() and
freeze_same_uuid() tests. With this change, both of them will deadlock while
running 'make check SERVER_MINOR_VERSION=8'.

I also think that if we remove these checks, we should also revert a follow-up
to it (http://svn.apache.org/r1593015). We did enable the shared data mutexes
for all platforms in order for the test suite to pass, but this is no longer
necessary, and I do not see any reasons not to restore the 1.8 behavior here.
