Hello, I may be wrong, but from what I see in lib/readline/history.c:stifle_history, every time stored history reaches HISTSIZE limit, the whole array keeping history data is rewritten (by moving each element one index further to make room for new entry. This is quite inefficient. Shouldn't we rather have a "0th_index" variable remembering where in the array the first element is and manipulate it?
Let me know if it's not clear what I mean and I'll elaborate. best, Jan
