My guess: "tail frame.log" closes its stdout as soon as it has read
the requested lines from the file, "tail -f frame.log" keeps its
stdout open, since it is waiting for new lines to be added to the
logfile. Cat is using some buffering on its stdin, so it tries to read
a buffer's worth of data at a time.
