In Racket, break-thread is used to send an break exception to a thread[1].
E. g.
(let ((th (thread (lambda ()
(dynamic-wind
(lambda () #t)
(lambda () (/ 1 0))
(lambda () (sleep 5) (display "out-guard\n")))))))
(sleep 1)
(break-thread th))
For above code, out-guard part of dynmaic-wind will not be interrupted if
use break-thread to cancel a thread, and kill-thread will cancel thread
immediately.
In Guile, the equivalent of kill-thread is cancel-thread, and is there any
equivalent of break-thread?
