This is a library and you have a choice here to goad your users into doing
the right thing.  Throwing from a destructor is just very very very bad idea.
Don't complicate the library just to make that weirdness a possibility.  It is
not worth it.  Even if it is free, don't allow it.  It is just just
wrong design.
