How to prevent a user from checking list of processes started by another user ?

In other words, how do I forbid a user to see which processes are running by another user ?

There are several ways to achieve that.

The oldest I know would be using a kernel with grsecurty patches applied, which bring restrictions for procfs

Another one would be the PID namespace feature of cgroups.

When available, I'd go for the last one, as it is the least intrusive one.
