Restricted Execution of untrusted code

[Emanuele D'Arrigo]

I noticed that this issue has been discussed in this newsgroup
periodically over the years and I seem to understand that -
comprehensive- safe/restricted execution of untrusted code in python
is currently quite hard to achieve.

What if the safety requirements are a little relaxed though? All I'd
want to prevent is for the code opening/damaging files, formatting
drives or similarly catastrophic exploits. I'm not particularly
concerned if the application freeze or crashes. Nor if the
application's objects are inspected and exploited. All I want is to
make sure that if somebody uses my application plus a third party
plugin for it, the worst that can happen is that they can't use my
application with that plugin.

Is that feasible?

Thanks for your help!
