- Fix slowness when operating over fast connections, where the timeout(9) granularity is on the same order of magnitude as the round trip time. timeout(9) can happen up to 1 tick early, which was causing receive ack timeouts to happen too early, causing bogus "lost" packets. - Increase the local time counter to 64 bits to avoid roll-over. - Keep statistics on memory allocation failures. - Add a new option to always include the ack when sending data packets. Might be useful in high packet loss situations. Might not.
