This arose from the standard check using NamesSystemGVars. It seems that that also returns Thread Local Variables so last and co might already be threadlocal. So we need a way to test whether a global is thread-local.

IsBound(ThreadVar.("foo")) returns true iff foo is thread-local variable.

Turns out you do need to look in the kenrel to get a correct answer when foo is UnBound. This is now all in a pull request. Incidentally, skipping thread-local variables reduces the number of thread-local objects in globals to about 70.
