Please check and see what the compiler generates for this before giving a patch
that deploys it in tons of places. I'm pretty sure that an empty virtual
function will indeed generate a static destructor, although a pointless empty
one. There's a good chance it will even change the virtual pointer on the
object.

Anyway, if the technique works that's fine but it's pointless to review a patch
to deploy the technique before you've tested it!
