It actually works for functions.  To support aliases, you can do

  preload() {
    local so cmd
    so=$1
    cmd=$2
    shift 2
    case x`type -t "$cmd"` in
      xalias) eval LD_PRELOAD=\$so $cmd \"address@hidden" ;;
      *) LD_PRELOAD=$so "$cmd" "$@" ;;
    esac
  }

  alias line-buffer='preload /t/linebuf.so'
