The use case Christoph described was an user-space number cruncher app that does some network I/O over RDMA IIRC. AFAICT, if he could isolate a physical CPU for the thing, there would be little or no communication with the non-isolated part. Yes, the setup sounds weird but it's a real workload although pretty damn specialized.
