So what is? What do the kernel developers recommend as a way to see if a file is written to, and that file happens to be a pipe? FTR, I've opened the symmetric Debian#1039488: https://bugs.debian.org/1039488 against coreutils, since, if this is expected, and writing to a pipe should not generate write events on that pipe, then tail -f is currently broken on most systems.
