    kernel - Reduce the size of the callout wheel
    
    * The callout wheel is per-cpu but ncallout is calculated based on memory.
      A system with many cpus tended to allocate an excessive amount of memory
      in aggregate for the callout wheels.
    
    * Reduce the size of the per-cpu callout wheel by approximately a factor
      of (ncpus).  On a 16G machine with 8 cores, aggregate callout wheel
      allocations is reduced from 128MB to 16MB.
