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.
Yes, but a solution with threads will have problems as well, since read() and friends will return EOF rather than block when you reach the end.
