    Thank you Shea,

    with a little change, adding "sleep 0.1" makes it hang early in all (few)
    linuces I tried: Let me know if this helps you reproduce the problem.

    As before, hangs under strace, does not hang under 'strace -f'. Sorry if I'm
    misunderstanding something.

    New script:


    rm -f $PIPE
    mkfifo $PIPE
    set -x

    spawn() {
    sleep 0.1
    echo DONE > $PIPE

    spawn &

    while true; do
    while read LINE < $PIPE; do
    echo $LINE
    spawn &
