Thanks, I've fixed those.  We don't have threadsafe by the way; only
safe/unusafe.  Safe also means threadsafe.

Not sure what you mean by threadunsafe.  Is it different from plain

We *want* the RTS to be able to be called by threads it doesn't expect.
Otherwise how do you implement a thread-safe library API in Haskell?
