Far more generic an issue than 'interface' alone.
That is actually the legacy of the queue architecture and its runners - not
originally designed for per-separate-domain or matched-to-interface use.
The same issue arises even with multiple, separate configuration files and
separate invocations of the (same) binaries.
The BFBI fix is to process only one outbound message at a time.
A more appropriate fix would require compile-time settings to use separate
storage areas - and more.
In that case, it is probably less of a maintenance hassle to leave each instance
bog-standard and just 'jail' them with fully separate resources and storage.
The longer-term fix is to alter the way the queue is structured (per-domain
and/or per-interface) and how runners traverse it (restricted to their own tree
only).
