python sandbox

[Uwe Schmitt]

Hi,

I wrote a simple sandbox for executing pyhton code in a
restricted environment.
The code can be downloaded from 
http://www.procoders.net/download.php?fname=SandBox.py
I appreciate any comments. I'm especially interested if
my restrictions are secure or if they can be circumvented.


Greetings, Uwe.
