  Log:
  A GEOM cache can speed up read performance by sending fixed size
  read requests to its consumer.  It has been developed to address
  the problem of a horrible read performance of a 64k blocksize FS
  residing on a RAID3 array with 8 data components, where a single
  disk component would only get 8k read requests, thus effectively
  killing disk performance under high load.  Documentation will be
  provided later.  I'd like to thank Vsevolod Lobko for his bright
  ideas, and Pawel Jakub Dawidek for helping me fix the nasty bug.
