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