Linux implements fork() via the clone() system call.
The clone() system call, in turn, calls do_fork().
The bulk of the work in forking is handled by do_fork(),
which is defined in kernel/fork.c.This function calls
copy_process() and then starts the process running.
If copy_process() returns successfully, the new child is
woken up and run. Deliberately, the kernel runs the child
process first.
