<p>A global descriptor is an object that represents an entity that is
owned by some process and may reside in an address space not
accessible to the currently-executing process. The global descriptor
consists of two parts: the <em>owner</em> of the entity, which is the
identifier of that process in which the entity resides, and a <em>local
descriptor</em>, that uniquely identifies the entity with the address
space of the owner.</p>
