That's fine, because doing that would be a mess anyway. Only one process
can read from a fifo, the first one to do the read() call would get the
data and the other would get nothing.

Sometimes you might need a dynamic number of applications to draw on the
movie. With chained filters you have to predict the maximum number of
apps before you start the movie, and you have to chain, say, 5 filters
even if you'll only need one. That makes the multi-fd approach much more
scalable.
