================================================================================

ADVICE: (for Remark #2120, ASL_MSG_SERIALIZED_REQUIRED): A named object is
created inside a non-serialized method - this method should be serialized. It is
possible that one thread enters the method and blocks and then a second thread
also executes the method, ending up in two attempts to create the object and
causing a failure.

TEST= Run FWTS.
