The next big piece of functionality in snapshot. There's a bit more grubbing around in the NT internals than would be nice, and it has made me start to question the value avoiding MinidumpWriteDump. But this seems to extract most of the data we need (I haven't pulled the cpu context yet, but I hope that won't be too hard.)
