Change the value of `laxy-highlight-max-at-a-time' to 1, to see no blocking (no competition with reading input). If you have it set to, say, 20, then up to 20 isearch matches will be lazy-highlighted before an already pressed additional `C-s' shows its effect by moving to the next search hit. This is very easy to see with symmetric folding turned on. Lazy highlighting occurs in bursts of `laxy-highlight-max-at-a-time' search-occurrence highlights, and after each burst ordinary search processing continues.
