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)

explicitly notify the switch when a link appears to be blocked in a send instead of assuming this is the case for all idle links. how we decide when it's really blocked still needs testing/optimizing

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
