Beyond the Alpha-barrier, he only thing I find lacking about the membar_*()
API is maybe a set of functions that would eliminate the #ifndef/#endif
repeated over and over when synchronization is done via atomic_ops(3).
I've been meaning to add preatomic_membar_foo/postatomic_membar_foo to
address this, since finding typos in the cpp conditional that went
undetected for years.
Not sure it's necessary to distinguish the pre/post cases -- Linux
does with smp_mb__before_atomic/smp_mb__after_atomic, but I'm not sure
that distinction is needed for all our membar_foos, and I haven't
taken the time to research the situation adequately.
