1. Trace the execution of the following. Indicate what is happening in the 
kernel at each stage. You may assume that process A has been started as the 
init process and has started no other tasks up to this point. 

Process A:

Process attempts to fork itself...

if the process is now the forked process, then execute Process B then
exit (which is never reached)

it then goes into a long loop allowing Process B to complete...
(this part I didn't understand...with the following line waitpid, it should
not have to loop, it would recieve a signal from B.)

it then wats for Process B to complete


Process B:

Gets it's id...

It then goes intoa  looping process that has an internal loop.  Both have an
incrementer, j and k respectively...

In the inner loop, j and k and added with 10..

if they add up to...

99994, then it gets its parent id...

99999, it gets the time form start and set it to thetime (i think)

100030, kills itself...


I am guessing, since the processes are just looping and not really accomplishing
much for the system, that the thetime variable is used later for a timing 
mechanism.  I think. :-)
