  BUG#27583 (slave sql fails to read from iocache when slave got
  stopped at pos==4):
  
  Submitting patch on behalf of Andrei, who discovered the problem
  and provided the patch.
  
  An update of the group relay log coordinates when rotating forgot to
  update the group relay log name and only updated the group relay log
  position (and group master log name and position).
  
  This patch adds code to update the group relay log *name* as well as
  the position 

  sql/log_event.cc@stripped, 2007-04-11 11:10:10+02:00, mats@romeo.(none) +3 -0
    Setting group relay log name as well when rotating, not just the group
    relay log position.
