    rx: Reverse the consumption order of idle queue
    Currently, the rx server thread idle queue is used in an LRU manner.
    This means that we round robin requests between all of the threads
    configured on a given system, which means that we end up thrashing
    CPU caches on machines whose workload doesn't require that all of
    the configured threads be used.
    Change this so that we always use the most recently idle thread. This
    isn't as "fair" to all of our waiting threads, but should mean that we
    scale better on SMP machines, as a thread that is recently idle is
    likely to have been recently scheduled.
    Performance numbers to follow ...
