Yes, but still the question remains open for non-empty classes
(e.g. want to use a 64bit useful payload), and for _emplacing_
any classes anywhere (e.g. on stack).
Afaiu, there's no solution except for declaring extern(C++) (yes,
i know, it's a hack), and it will not work, if a class is
templated on something which can not be cpp-mangled. So the
question is: is there any reason why this is not possible? I
mean, maybe this question was closed long before.
Also, do shared classes actually require monitors?
