Is it a complete freeze (i.e., you need to use C-g to get out of the loop) or a slowdown of a couple of seconds? The former is a bug. However, some changes in the buffer imply a massive loss of the cache (e.g., inserting a block clears cache in the whole section), so the next action can be slow since you need to fill it again, hence the slowdown. > At that moment I cannot > start the profiler.

However, the best way to know is to look at it. Regards,
