I think this is about as good as we're going to get but we're very near the merge window now so I'll leave this until after the merge window is done in case there's more review comments before applying. I need to reread the implementation code a bit as well, it looked fine on a first scan through but it's possible I might spot something later. --jousvV0MzM2p6OtC Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl12JBkACgkQJNaLcl1U h9A12AgAgjBaLkxqsVW5TL56eMjLxX9dEojMe22QzVUBeRfLcXLRQ0M/5AJqvzf4 AEmOsHlPLqh/SKRoVfOa4Xr2h/Zaiz6wzCcvsLxe3B9P7MYg0/9kyHiDEjGExuq4 X1r18hLuMKsWjBmrWoojtSGlQd5pbpmRdVPDseF+ved5Gp4S78KKx2gDZxYGuiy6 JB9LDRvsELfSndCxCJAC6s5BTb4uSmlVOB4gyzWR31XZXtNwIT4lz0eLUlaI0UBW ckxeMzTSeBRrQ5vQMm/1ZwjYh7hdhQYlWn3minuDj5FWwgVj754fdoi/2+rW7FaU 27xyj6cr4VIcQXWmU3DylfAbe+qE8Q== =eS/Q -----END PGP SIGNATURE----- --jousvV0MzM2p6OtC--
