Sorry, I was misguided. What was slow wasn't `line-number-at-pos' but
redisplay (so only the result of evaluation showed up delayed). This
long time for redisplay does only happen with some code I'm currently
developing, but also only when cache-long-scans is non-nil. Anyway,
I'll tell you when I have a recipe.
Thanks,
Michael.
