You may not want a container of polymorphic pointers to exceptions, but
you still want to catch exceptions polymorphically (else why bother
having an exception hierarchy at all?).

Since std::exception already has a virtual function (what()), there's no
per-instance space overhead in having a virtual dtor as well.
