It's a program to measure the actual cost of context switch (that AFAIK
is equal for different thread or different processes). The same program
may be written with shm and fork.

However I cannot believe you don't see the benefits of a multithreaded
approach:
- big improvement for components that can run in parallel on SMP
machines
- greater crash safety
