// On Win95 and on NT client, a queue handle which is returned to
// application is a pointer to this structure. The reason we keep the three
// handles is that doing RPC with context handle serialzes the calls. This is
// OK for all calls except MQReceive(). (a pending receive will block all
// future calls with the same handle, so we can't even close the queue).
// So, MQReceive() uses the binding handle and give the QM the context it
// expects as a DWORD.  Rt get this QM context when opening the queue.
