But the write didn't fail here. Instead, a signal was sent to 'tee'. If you 
don't want the signal, trap it. E.g.:

trap '' PIPE
for i in {1..300}; do
    echo "$i"
    echo "$i" >&2
    sleep 1
done | tee >(head -1 > h.txt; echo "Head done") \
 >(tail -1 > t.txt) >/dev/null

will give the behavior you want.

So there is no deviation from POSIX here.
