P.S. so this is the fixed version:

function read-timeout {
  local _read_timeout_buffer=
  local _read_timeout_c
  while IFS= read -t "$1" -r -n 1 _read_timeout_c || [[ $_read_timeout_c ]]; do
    _read_timeout_buffer+=$_read_timeout_c
  done
  read "${@:2}" <<< "$_read_timeout_buffer"
}
read-timeout 2 -r x < <(echo -n a; sleep 1; echo -n b; sleep 1; echo
-n c; sleep 1; echo -n d)
echo "$? [$x]"
