Description

The ttms log variable logs until the last byte has been written to the socket. For some applications it'd be useful to track the download time until the last ACK has been received (or has timed out). It's possible that the tcp_info data structure would have this information.

The (obvious) disadvantage is that connection might have to linger for a long time before it can be finished and logged. Not sure if there's a reasonable work-around for that.
