It is true only if the fifo already exists.  That is, if you did

        a lot of &&
        commands &&
        before &&
        mkfifo fifo &&
        feed >fifo &

        git diff -Ofifo
the consumer may attempt to open and read fifo when the other
process is still running a lot of commands, no?
