[netperf-talk] affinitizing netserver threads

[Matthew Faulkner]

That option set the affinity for the whole netperf process. I needed to set
the affinity for the threads / processes (server or clients) within
netperf, i.e. have two servers but running on different cores at the same
time. Also I needed it to output the results coherently.
