As called the patent is Win32 x86 specific implementations, IANAL.

Charles Davis had been working on implementing x64 EH. I don't know
how they work.
Ruben, I suppose Kai has been working for x64 EH, right?
(it is dw2-like implementation, IIRC)

Anyway, would you like us to implement sjlj on win32 x86?
