I thought about spinning up a VM, but I'm not sure if it would be
sufficiently equivalent to the OzLabs set up to actually hit the bug...

I think hitting the issue it's due to a combination of OzLabs and
Buildroot features:
 - how quickly the buildroot mailing list sends mail
 - how quickly ozlabs receives it - both in terms of mail system lag and
   just in terms of network locality
 - how many cpus ozlabs has to parallelise processing, etc
I don't think I can get an OzLabs like virtual machine for very long
without spending a *lot* of money.

I think this is probably the way to go, but it's worth noting that as
always I'm not at OzLabs any more :)
