I wanted to do more benchmarks and possibly try to produce better
solution than my initial patches, but I had no time for this yet. I
think there is big potential for performance improvements, though I'm
still not sure how it could affect different hardware and different
applications, that's why I decided to look into it more thoroughly
later. But I think restoring the old way is safe. I'm OK with this
