Description

It loads fine on 4.3.0 and on 4.3.7, as far as I could test. On 4.4.0 it just hangs and eats CPU after (use sandbox) (using csi -n).

Reported by Vesa Kaihlavirta (vegai) on IRC. I could reproduce it on my machine (Debian stable, x86).

The problem seems to be an optimizer bug that replaces a call to `real-make-safe-environment` with a definition that is redefined later.

I have changed the sandbox code to use `defstruct`, but it seems the test doesn't work. I'm not sure if that was like that before this change.

Please give the current `trunk` version of the sandbox egg a try.
