But you ship code with sun.misc.Unsafe :-)
As it stands, sun.misc is the place in which non-standard but
universally implemented, platform related, expert-user-only APIs reside.
So seems to be the least controversial home for it. The main
difference is that you won't be able to treat is as assumed to
be present until JDK8. But this is also true of some other
things like upcoming getAndAdd intrinisification.
I'd conclude by saying that other suggestions are welcome, but
they aren't welcome by me :-) This seems like the only
packaging that no one feels like they must try to veto .
