The cvs seems to have a bug in making a shared array from what's
already a shared array,
(define a #2((1 2 3) (4 5 6) (7 8 9)))
(define s (make-shared-array a (lambda (i) (list i 1)) 3))
(display s) (newline)
(define t (make-shared-array s list '(1 2)))
(display t) (newline)
"s" is a shared array which is column 1 of "a", ie. (2 5 8). "t" is
meant to be range 1 to 2 of "s", ie. (5 8), but it comes out as (4 7).
#(2 5 8)
#1@1(4 7)
This works in 1.6, so I'm guessing it's some recent regression.
