Use the client id to alternate the static_vcs balancer (-b context)
across clients - otherwise all clients end up on vcs0 and do not match
the context balancing employed by media-driver.
This may want to be behind the -R flag, but I felt it was a fundamental
property of static context balancing that to keep it disabled by default
causes unfair comparisons and poor workload scheduling, defeating the
purpose of testing.
