  We present the Round Handle Problem, proposed by Freedman and Krushkal. It
asks whether a collection of links, which contains the Generalised Borromean
Rings, are slice in a 4-manifold R constructed from adding round handles to the
four ball. A negative answer would contradict the union of the surgery
conjecture and the s-cobordism conjecture for 4-manifolds with free fundamental
group.
