I got atomic_ptr working on powerpc.  The RCU stuff worked with only
a recompile so OS-X Darwin has a pretty clean pthreads implementation.
While Linux preempts even when you don't want it to, Darwin has the
opposite problem.  It doesn't preempt even when you do a sched_yield().
I had to set SCHED_RR to get the threads to interleave.

I need to look at the membar stuff a little more in depth and decide
what the atomic primatives api should look like.
