You should be able to detect if the stream is seekable (by checking the result of 'lseek(fd,0,SEEK_CUR)') and only buffer if it's not.
Of course, if you're really paranoid, the file could get changed out from under you. But honestly you're probably screwed either way with an attacker who can do that.
