-   function calls anyway, and the caller should be able to deal with it.
-   This is a security risk, of course, as `internal' values may leak out
-   after a system call, but that certainly doesn't matter very much for
-   a processor with no MMU protection!  For a protected-mode kernel, it
-   would be faster to just zero those registers before returning.  */
