guys, we can think of zombie process as a GHOST. when a
person (having some unfinished business on earth) dies they
become ghost, means they are dead but they have there
existence on this earth. Just like that if a process died
but it's existence remains in the process entry table then
that process became Zombie.

now who is going to clean this mess?
so it is the work of the parent process to clean this thing
by waiting on the child process.
if the parent process don't clean up this mess then it would
be the work of operating system to release these resources
when process entry table would be looked up again
