Something like that may be needed to handle the case where there is
simply not enough CPU to go through multiple SAE exchanges concurrently.
I'm not sure the exact approach used here is the best way of doing that,
though, since I'd expect some cases to end up blocking peers in a way
that results in blocking progress, e.g., when A wants to talk to B first
and B to C instead of A.
