The theory is that Nt knowledgeable pepole could maintain a backend Nt*
layer and everyone else could write to the standard Win32 API vs.
exposing the Nt layer to everyone and requiring that people figure out
the unfamiliar Nt* arguments if/when they want to make changes.
But, Corinna and I haven't finished discussing how this would work yet
so there are no guarantees how or if this will happen.
