This is pretty straightforward, actually.
Queue 1: batch.q
slots: N
subordinates: interactive.q (max slots 1)

Queue 2: interactive.q
slots: N
subordinates: batch.q (max slots 1)

As soon as one job is submitted to a host instance of batch.q, the interactive.q
on that host is subordinated (disabled), and vice versa.
