It seems that boost::variant has non-trivial destructor even for something
like boost::variant<int32_t, int64_t>. Thus, It cannot be used in
situations that call for a POD where calling the destructor is trivial.

Particularly, I can't have a boost::lock_free::queue<boost::variant<X, Y>>
even both X and Y are trivially destructible.

How about making boost::variant trivially-destructible when everything in
it is trivially-destructible?
