I read that, and grepped through the code, and the Racket 5.0 sources.
Every use I found outside of some contrived test cases in Racket is of
the form

(thread-resume t (current-thread)).

I understand the semantics of (thread-resume t1 t2), where t2 is not
the current thread; the paper and documentation explain that.  What I
don't understand is why one would ever do it.
