In C++03 it was always best practice to *always* wrap your 
destructors in a try...catch clause. Now it's somewhat mandatory.

As an aside, we could really do with some new compiler warnings on 
this actually. I already get caught enough times forgetting to mark 
move constructors as noexcept, without which some STL implementations 
will silently disable move construction completely.
