This code snippet causes the REPL input to hang until you ^C:
(call-with-current-continuation
(lambda (k)
(create-thread k
(lambda ()
(call-with-current-continuation
(lambda (j)
(within-continuation k
(lambda () (j #f)))))))))
Weird. I don't know what's going on there -- obviously something's
spinning somewhere, but it's not clear what. All that should happen,
I think, is that the REPL should proceed normally and the thread you
created should terminate without doing anything. But the REPL thread
starts to spin somewhere until it gets a thread event or interrupt.
`C-c t' in an interpreted world suggests that it is spinning in a
state space transition, which would not be surprising; I'm not sure I
believe our state space transition algorithm or semantics...
