  We show that homological stability holds for the family of Iwahori-Hecke
algebras of type B_n, where homology is identified with the relevant Tor group.
This family of algebras is related to the Coxeter groups of type B_n, which are
groups of signed permutations. The result builds on Hepworth's result for
Iwahori-Hecke algebras of type A_n.
