Title: Fix build for G++ 4.8.2 (Fedora 20)

The issue here is that G++ warns about a potential misuse of delete on a
polymorphic object which the base class hasn't a virtual destructor. In
our code that's not a problem because by design, we make the destructor
protected so we can't delete "by the base class pointer type".

However G++ is being picky here, as described in
http://gcc.gnu.org/wiki/VerboseDiagnostics#delete-non-virtual-dtor "the
warning will sometimes be issued for correct code". The workaround of
marking the class final is not widely available yet, so we live with the
simplest fix.
