Actually, this is not the common case. The common case is that the programs writing to (and reading from) the pipe use stdio; when writing to a device that's not a tty, stdio defaults to block buffering. The block size used by stdio should work well with Linus's scheme (and if it doesn't, it would probably make sense to change it).
