You're wrong. I am implementing a solution that allows two
methods -- one (SHDR) that needs an seek (but an continuous one
so it's likely served from the track buffer) but has some advantages
and another one (PHDR) that does not require a seek.
You two are arguing a method that always requires the seek
and has a couple of other drawbacks as earlier discussed too.
