All the above is correct.  Defaults.PERMITINTERRUPTS is final as a

What version btw?  In CVS, the following works:

SISC (1.8.1-alpha) - main
#;> (define (go)  (go))
#;> (import threading)
#;> (define t (thread/new (lambda () (go)))
)

finished-with-error

If I've got the version right, then it would seem like something else is

Yes.  The manual for 1.8 should be accurate on this.
