Actually, if I understand it correctly, OopStorage already gives us full barriers, so we should be covered, and we can
simply revert JDK-8251451: http://cr.openjdk.java.net/~rkennke/8247281-shenandoah.patch
(Is there a better way to propose amendments to a PR?!)
I believe this probably also means that we don't need to scan object monitor lists during thread-scans, and let SATB
(or whatever concurrent marking) take care of it. @fisk WDYT?
