In old Unix, creating a new process is much more expensive than creating a
new thread, because the child process needs to copy parent's address space.
In modern Linux, fork() uses copy on write, and thus has similar performance
to pthread_create(). Plus they use the same syscall clone(). | w*s

harder ?
