try using a simpler FIFO order for each backpressure buffer, since there are other mechanisms to penalize the flooding node, leads to better TCP throughput without affecting traffic between other nodes (does affect traffic in the same session, but there's hypothetically workarounds to that)

switch to a separate queue per stream of traffic, FIXME for some reason this makes distance calculations more expensive in handleIdle?
