Using ptrace to write a program supervisor in userspace

I'll looking for advice/resources to write a program that can intercept system calls from a programm to supervise it's filesystem, network, etc access.

The aim of this is to write an online judge, so that untrusted code can be run safely on a server.

This is on linux, and I would prefer to write C++ or a scripting langauge (ruby, python, etc), and a library would be great!

Thanks.
