Jonathon,
thanks for your feedback.

I am unsure where to located such a configuration option in the gust
domain XML.

A few thoughts:
1) introduce a new emulator-options element in devices and a run-with
child element with a parameter async-teardown, e.g.
...
<devices>
   <emulator>/usr/lib/bin/qemu</emulator>
   <emulator-options>
     <run-with async-teardown='on'/>
   </emulator-options>
</devices>
...

2) introduce a new run-with element with a parameter async-teardown in
domain, e.g.

<domain>
   ...
   <run-with async-teardown='on'/>
   ...
</domain>

Any ideas and suggestions are welcome.
We usually use domain <features/>, e.g.:

<domain>
   <name>someName</name>
   <uuid/>
   ...
   <features>
     <acpi/>
     <tcg>
        <tb-cache unit='KiB'>102400</tb-cache>
     </tcg>
   </features>
   ...
   <devices/>
</domain>

This looks like a fit place if we want to expose this in the domain XML.
And from the qemu-options.hx file it doesn't look s390x specific, which
means, we don't need to make the new element arch specific. IOW we can have:

   <features>
     <async-teardown enabled='yes'/>
   </features>
