 If that last command doesn't work for you (with an error like: "error while loading shared libraries"), run the slightly-different command below.
 This is because, for security reasons, we need to manually pass `*PATH` environment variables for some shared libraries to be found (see [this explanation](https://unix.stackexchange.com/a/251374)).

 $ # terminal 2

 Once the experiment is done, in the first terminal, press enter again to stop tracing.
