JEP 171: Fence Intrinsics

[David Chase]

Is this the right place to comment on this?
I think these should not go in Unsafe; fence intrinsics belong with compareAndSet in j.u.concurrent.atomic.

My reasoning is that there are some lock- or obstruction-free algorithms that do require CAS and (in some cases) fences, but do not require anything that is actually unsafe, and do not require the security clearance that goes with being allowed access to Unsafe.
