I doubt that the case that the ref count raises from 0 to 1
can occur. uno_ext_getMapping returns an acquired mapping. Every time
that function is called then a new mapping is created. Following the
rules of ref counted objects, then if the ref count is null no one has
a reference to the object anymore. Hence no one can call acquire. If someone
calls acquire then they must have kept an unacquired pointer which is
illegal.
