replace the send-to-self with a timer and an arbitrary timeout; i don't really like this but it seems to work better (1 ms is fast by human standards but an eternity for a syscall or the scheduler, so i think that's reasonable)

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

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
