(exactly, for the bug in 4.1 reported in this bug report). We just make
Load_log_event work like Query_log_event for temp tables.


sql/log_event.cc:
  For LOAD DATA INFILE to be preceded by SET PSEUDO_THREAD_ID if needed, in the mysqlbinlog output,
  we need to use the LOG_EVENT_THREAD_SPECIFIC_F flag in Load_log_event exactly like we already do  
  in Query_log_event.
