message:
  branches/zip rb://147
  
  Done away with following two status variables:
  
  innodb_buffer_pool_read_ahead_rnd
  innodb_buffer_pool_read_ahead_seq
  
  Introduced two new status variables:
  innodb_buffer_pool_read_ahead = number of pages read as part of
  readahead since server startup
  innodb_buffer_pool_read_ahead_evicted = number of pages that are read
  in as readahead but were evicted before ever being accessed since
  server startup i.e.: a measure of how badly our readahead is
  performing
  
  SHOW INNODB STATUS will show two extra numbers in buffer pool section:
  pages read ahead/sec and pages evicted without access/sec
