Define the need of process relative handles

Define the need of process relative handles.

The most significant purpose was robustness. When kernel object handles were system-wide values, one process could simply acquired the handle to an object which another process was using and wreak havoc on such process. The other reason for process-relative handles is security. So, Kernel objects are protected along with security, and a process should request permission to control an object before attempting to manipulate this. The creator of the object can prevent an unauthorized user by touching the object simply by denying access to this.
