So, it's not DCE threads, it's no threads at all. Which is okay.

Someday I need to come up with a better error message there.
The library needs to know how to do atomic integer operations, and
if it doesn't have any information for a particular target, that's
what happens. For some reason we give an error rather than choosing
the generic implementation. (Maybe because the generic version isn't
necessarily atomic?)
