that's how a typical OS kernel implements it. If seek() is bad on
GzipFile, how hard would it be to fix this?
I'd imagine that there's no easy way to make arbitrary seeks on a
GzipFile fast. But wouldn't it be enough to

objects, due to the overhead of calling read() with very small values),
it occurred to me that the prefetching facilities offered by
BufferedIOBase are not flexible and efficient enough.
Indeed, if you use seek() and read(),
