[Python-Dev] Reviving restricted mode?

[matsjoyce]

Unless you remove all the things labelled "keep away from children". I wrote 
this sandbox to allow python to be used as a "mods"/"add-ons" language for a 
game I'm writing, hence the perhaps too strict nature.

About the crashers: as this is for games, its "fine" for the game to crash, 
as long as the sandbox is not broken while crashing.

time and math can probably be allowed, but random imports a lot of 
undesirable modules.

My sandbox doesn't use proxies, due to the introspection and complexity that 
it involves. Instead it completely isolates the sandboxed globals, and checks 
all arguments and globals for irregularities before passing control to non-
sandboxed functions.
