[racket] big-bang bug when creating racket distribution executable?

I can confirm the behavior, which is visible under both *SL and Racket and all methods for creating executable. 

For a workaround, use this for now: 

#lang racket/gui

(require 2htdp/universe 2htdp/image)

(define (render ws) ws)

(define (halt ws) #t)

(big-bang (rectangle 600 400 'solid 'gold)
          (to-draw render)
          (stop-when halt render))

(yield (make-semaphore))

However, running the racket executable created for distribution closes the window and returns you to terminal as soon as stop-when is returns true, thus bringing the execution to a jarring halt without adequately displaying the final image (it’s hard to tell whether it displays because the action is so quick). This appears to be the case for both Windows and Mac installers. Is this a bug or how the process is designed to work?

I can probably achieve this with some finagling of the world state, but the two different behaviors between Dr Racket and distribution was surprising.
