Does unsafe code raise an exception?

[Geoff Goehle]

I was following the readme for this and under the Using CodeJail section it mentions that the unsafe code should throw an exception. When I tried it the code did not print out the files in /etc, but it didn't throw an exception either. I didn't know if I'm incorrectly configured or if things have changed. One thing I had to do was

codejail.jail_code.configure('python', '<SANDENV>/bin/python','sandbox')

instead of the written

codejail.jail_code.configure('python', '<SANDENV>/bin/python')

Can you tell me the reason？
Now I'm getting the same problem… so confused
