Undo half of the previous change :-( Setting interp->builtins to the __builtin__ module instead of to its dictionary had the unfortunate side effect of always running in restricted execution mode :-( I will check in a different way of setting __main__.__builtins__ to the __builtin__ module later. Also, there was a typo -- a comment was unfinished, and as a result some finalizations were not being executed. In Bart Simpson style, I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes.
