You started with one process, then two processes that forked into 4 processes, three total fork calls. For the second fork, two were parents and two were children. Welcome to multiprocessing. Each process has its own copies of the variables. For instance if the first process was 1000, it forked off 1001 and then 1002, and 1001 forked off 1003. Actually, as I recall, the child tends to run before the parent of a fork, so 1001 might have forked 1002 before 1000 could, so it forks off 1003, but you can tell from the order of the printouts.
