                     15: is the only way new processes are created.
                     16: The new process's core image is a copy of
                     17: that of the caller of fork____; the only distinction
                     18: is the return location and the fact
                     19: that r0 in the old process contains the process ID
                     20: of the new process.
                     21: This process ID is used by wait____.
