Ksh and Kcl (Kyoto Common Lisp) both have/had problems with assuming
that all _iob's are always contigious.  What *is* the "approved"
method of finding all _iob's?  I have used the internal 4.3BSD libc
function findiop:_fwalk(function) to walk over and close all but the
first 3 _iob's.  Is there *legit* way to do this?
