You are aware that I wrote "usually" there?

But sometimes the effort vs performance trade of is worth it. E.g.
opening a log file in 10 seconds vs nearly none make a difference (as I
said, I don't remember the exact speed up anymore, but it was
significant; but also not the only problematic point as originally the
opening of a large enough log file took minutes :P ).
