Doesn't select() effectively busy-wait on "real" files (pipes and file descriptors obtained via open(), as opposed to network sockets) on most (all?) UNIXen? At least this has been my finding under Linux.

select() doesn't make sense for regular files, so tail -f can't use it. For Unix pipes, it works as advertised. On Windows, it only applies to sockets.
