 Description   

Data comes from Sandy Bridge system running sysbench OLTP RO in 1 thread against 1 table.

Time spent for function call convention. All this function does is proxy call to THD::reset_for_next_command(). There's also a comment:

  @todo Remove mysql_reset_thd_for_next_command and only use the
 
  member function.
