Rust demonstration of setting thread affinity with pthread_setaffinity_np

Call this program with -s N to set a specific CPU. Without -s, the thread will have the default affinity.

This program will print out the main threads CPU, the child threads CPU and the child threads affinity after optionally setting it.
