How about ONLY adding to TLR? Several potential objections come to mind: - The above TLR formulation puts a ThreadLocal.get on the path to every random number. Is that an overhead we need to impose on the serial case just so people don't shoot themselves in the foot in the parallel case?

BTW, this issue may go away. On the todo list is to place this and others into package-private j.u.c.ConsolidatedThreadLocal, and then explore adding a direct link to it in class Thread.

(The consolidation will help deal with an increasing number of TLs used in basically similar ways in different classes. Some of these could use exactly the same fields so would reduce footprint.)
