boost::thread and std::thread don't know what the native thread type
is, nor do they know that Windows has two native thread types. The
correct solution seems to be:

struct native_handle_type
{
  HANDLE handle;
  DWORD id;

  // perhaps, for backward compatibilty
  operator HANDLE() { return handle; }
};

In other words it's a QOI detail.
