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