 260  *    if a call to QueryInterface for a pointer to a specified interface
 261  *    succeeds the first time, it must succeed again, and if it fails the
 262  *    first time, it must fail on all subsequent queries.
 263  *  * It must be symmetric ~W if a client holds a pointer to an interface on
 264  *    an object, and queries for that interface, the call must succeed.
 265  *  * It must be reflexive ~W if a client holding a pointer to one interface
 266  *    queries successfully for another, a query through the obtained pointer
 267  *    for the first interface must succeed.
 268  *  * It must be transitive ~W if a client holding a pointer to one interface
 269  *    queries successfully for a second, and through that pointer queries
 270  *    successfully for a third interface, a query for the first interface
 271  *    through the pointer for the third interface must succeed.
