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.)
