  I discuss the effect of resummation of soft gluons in hadronic production of
high mass systems, and in particular in heavy flavour production. I show that
in widely used $x$-space resummation formulae, spurious terms that grow
factorially in the order of the perturbative expansion are present. These terms
spoil the convergence of the perturbative expansion. I also show that it is
possible to perform the soft gluon resummation in such a way that these terms
are not present. Implications for top and high mass dijet production at the
Tevatron are discussed.
