Note that N2179 doesn't require a copy to be made. If GCC allocates the
exception objects on a heap - I have some recollections that it was doing
that but I may be wrong - it might still be possible to implement
current_exception to return a pointer to the active exception object... if
there's a way to insert a reference count somewhere inside.
