Is this a problem in Lisp? I know in C that's an issue since you're just calling close on an integer but I had thought lisp would handle that more gracefully. Although I guess the behavior isn't specified since saving an image is outside the spec?
Lisp and C use the same API to the OS so it's the same problem and there is no general solution.
The problem with cleaning up _before_ saving the image is that you can't use the image any more. I was hoping to have a solution that didn't require an exit and restart every time an image was dumped.
On Unix, one trick is to fork before saving. In the child process, clean up OS resources, dump the image and exit. The parent process continues normally.
