echo "Backgrounded pipes shall have their stdin redirected to /dev/null"
# 1. bash does not redirect stdin to /dev/null if it is interactive.
# hush does it always (this is allowed by standards).
# 2. Failure will result in this script hanging
cat & wait; echo Zero:$?
# This does not work for bash! bash bug?
cat | cat & wait; echo Zero:$?
echo Done
