Introduce test 'test_proc_pid_mem' to address the issue in the TODO.
Check if VMsize is 0 to determine whether the process has been unmapped.
The child process cannot signal the parent that it has unmapped itself,
as it no longer exists. This includes unmapping the text segment,
preventing the chil
