Yes; not only is it the technique that allows covering this
borderline-misuse case without slowing down others, but it also
makes for simpler code.
And even on those machines not natively supporting, the internal
CAS or LL/SC loops to implement are likely faster than what we can do
from Java. I plan to update some other j.u.c classes to use it when
applicable (although not immediately).
