We were getting unbalanced AddRef/Releases on Direct3D9 apps running on Windows 8 that ran fine on Windows 7. Windows 8 seems to be doing somthing funky with the internal ref count of IDirect3DDevice9. For now, piggyback on the orignal ref count methods to be able to determine when to release ourselves. And cross our fingers that we won't be getting useless ref counts from some other overlay. This is a band-aid solution until we find something better.
