After some comments from David Holmes (thanks David!) I added internal comments about race conditions.

I refreshed the webrev with the additional comments.  I also changed one variable to be volatile, with a paragraph of comments explaining why.

(The change to volatile will inhibit CSE of ClassValue.get calls, but I think such CSE was unlikely anyway.  There should be no other performance effects.)
