Talking about performance, what about a 64bit 4.7.2 release with seh, out of your hands?

In terms of pure C++ eh stuff, that should be near or better than 32-bit dw2, that is to say, it should show a similar improvement vs 64-bit sjlj as dw2 shows on 32-bit sjlj.

If anyone wants to do a short benchmark, I think we'd all be very interested ;-)
