   9  * CSRSS is a native application and can only implicitly link against native
  10  * DLLs. Since e.g. user32.dll and gdi32.dll are win32 DLLs and not native
  11  * DLLs it is not possible to call functions in those DLLs directly from
  12  * CSRSS.
  13  * However, it is possible to explicitly load a non-native DLL. Such a DLL
  14  * can then in turn be implicitly linked against other DLLs in its own
  15  * subsystem.
