-/// If isFile is true, then this lookup should only return success for files
-/// (not directories).  If it is false this lookup should only return
-/// success for directories (not files).  On a successful file lookup, the
-/// implementation can optionally fill in FileDescriptor with a valid
-/// descriptor and the client guarantees that it will close it.
