I think, a more appropriate name is std.native 
(std.native.process etc). This package would strive to be 
platform-specific for the sake of efficiency rather than 
cross-platform. If someone doesn't need to be cross-platform, he 
needs an efficient interface to the native efficient capabilities 
of the current platform. That said, the content of std.native 
modules will be platform-specific and will provide comprehensive 
D-ified API for the platform features.
