Yes there are more inconsitencies like this through the code - but in my
replicator case I've added 'extra' loop around this interrupt check - thus
I've added this fix at this place.

The problem with interrupt check may be possibly bigger - as the semantic is
not really clear - should we always return 'error' when Ctrl+C is hit by the
user? - maybe we should check for sigint before we actually want to iterate
next loop - thus if the 'break' was noticed after processing last loop - we
return 'OK' like no break was seen ?
