You've just flubbed a little more. Your initial post dealt with the error
message from "status". "create" expects a function, true, but says so:

> th=coroutine.create(42)
stdin:1: bad argument #1 to 'create' (function expected, got number)

Returning to the fact that "status" says it expects a coroutine. I agree that
the error message should say that it expects a thread, because it only tests
whether it gets a thread, and that's enough. It also works if you pass the
main thread, not only a thread created by coroutine.create.
