Will be used later. You might wonder why the code uses a lame hash table to link the client object handles to the user mode pointer, when it should be clear that a *client* object should have a user mode attribute, like other objects, that we can use, especially since that is the only real purpose of that object. Well, tell that the MS developer, who implemented client objects without a user mode attribute...
