But doesn't that only happen if ./foo exits prior to echo being able to
push all its output? I guess if the shell can't handle the input, it will
exit early, but maybe we could write this as:
echo '...' | { ./foo 2>/dev/null; as_status=$?; cat >/dev/null;
test $as_status = 0; }
so that there is something to consume all of the echo output? But I don't
think we have to worry about this unless we get actual reports of a noisy
echo.
