Log Message:
membar_ops(3): Add some automatic tests.

These tests run two threads for five seconds each to try to trigger
races in the event of broken memory barriers.  They run only on
machines with at least two CPUs; on uniprocessor systems there's no
point -- the membars can correctly just be (instruction barrier)
no-ops.
