  We continue our study of the topology of the spaces of $m$ tuples of real
polynomials with common degree $d$ and without common roots of multiplicity
$n$, and in particular their stability properties with respect to $d$. In an
earlier paper we have proved a homotopy stability result and determined the
stable homotopy types of such spaces in the case $m n >=4$. In the case $m n=
3$ we could only prove stability in homology. In this paper we prove the
corresponding homotopy result for the case $(m,n)=(3,1)$. in the appendix we
also deal with the case ${m,n)={1,2}$.
