> If you drop the attached perf stacks into flamescope, you can see that
> mesos::internal::master::Slave::hasExecutor occupies 37% of the overall
> samples!
> This function does 3 hashmap lookups, 1 can be eliminated for a quick win.
> However, the larger improvement here will come from eliminating many of the
> calls to this function.
> This was reported by [~carlone].
