send a switch message immediately when peering, and use OS-level TCP keep-alive (shouldn't matter right now, since we have application-level keep-alive that preempts it, but important later)

rearrange tcp reading loop
...
according to documentation of io.Reader interface,
"Callers should always process the n > 0 bytes returned before considering the error err. Doing so correctly handles I/O errors that happen after reading some bytes and also both of the allowed EOF behaviors."

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)
