when we detect we're blocked, only drop packets often enough to make sure the existing queue's size is non-increasing, and always drop the worst packet from a random flow with odds based on the total size of packets queued for that flow

when a link becomes idle and packet are buffered that the link could send, send at least 65535 bytes worth instead of 1 packet, this reduces syscall overhead when small packets are sent through the network

allow links to send multiple packets at once, currently we still only bother to send 1 at a time from the switch level

when we abandon a link because we already have a connection to that peer, only wait for the connection to close if it's an *outgoing* link, otherwise incomming connection attempts can cause us to leak links
