can't fire and forget from a list - looking for other options

[Larry Fast]

I'm trying to work around the following limitation: lookup plugins (with_*) cannot be used with async tasks

My objective is to startup a set of listeners on a set of servers using socat.  My thwarted plan was

Host_vars/hostname

   listeners: [234, 567, 890]

  - name: setup listeners

    command: socat TCP-LISTEN:{{ item }},crlf,fork GOPEN:/dev/null

    with_items: listeners

    async: 10

    poll: 0

Any suggestions on how I could rework my approach?
