In fact, the extra code in ksh is not really this at all - it just
implements a slightly modified version of shl to run under (as in "below")
ksh, though I havn't bothered looking to see exactly how it differs from
the standard shl.
It certains *isn't* a case of the sxt layering stuff being understood 
directly by ksh.

PS. If anyone does go about putting this stuff *inside* a shell, they'll
    have the nice experience of finding out just how dishonest the manuals
    are when it comes to describing things like sxt(7), setpgrp(2), termio(7),
    etc... :-)
