> Currently, many critical thread pools are sized according to the number of
> available processors i.e. Runtime.getRuntime.availableProcessors() (See
> StageManager.java)
> In a multi-instance deployment, multiple Cassandra instances will
> independently assume that all processors are available to it; there should be
> a mechanism to specify a smaller set of processors (and perhaps have
> affinity).
