+
+       killed_status= thd->killed; // get the status of the volatile

+    at a particular time - at the time of the end of per-row loop in
+    our case. Binlogging ops are conducted with the status.
+
+       error= (killed_status == THD::NOT_KILLED)?  error : 1;
+    
+    which applies to most mysql_$query functions.
+    Event's constructor will accept `killed_status' as an argument:
+    
+       Query_log_event qinfo(..., killed_status);
+    
+    thd->killed might be changed after killed_status had got cached and this
+    won't affect binlogging event but other effects remain.
+
+    Open issue: In a case the error happened not because of KILLED -
+    and then KILLED was caught later still within the loop - we shall
+    do something to avoid binlogging of incorrect ER_SERVER_SHUTDOWN
+    error_code.
