Comment:

 Replying to [comment:7 arma]:
 > If these log lines could tell me which outgoing connection (aka which
 incoming socks connection) these messages were for (even just saying a
 SocksId number or something), then when I'm watching to see how it
 recovers, it will be easier to tell when snowflake is handling messages
 for the *old* connection, vs when it is using the new connection.

 Thanks for testing. This suggestion isn't so easy currently, because the
 bandwidth logger is per snowflake, not per SOCKS connection (per KCP/QUIC
 stream). But for now I can add stream numbers to the log and log when each
 stream begins and ends. KCP uses odd integers for stream numbers and QUIC
 uses even.
 {{{
 ---- Handler: begin stream 3 ---
 ---- Handler: begin stream 5 ---
 ---- Handler: closed stream 5 ---
 ---- Handler: closed stream 3 ---
 }}}
 {{{
 ---- Handler: begin stream 0 ---
 ---- Handler: begin stream 4 ---
 ---- Handler: closed stream 4 ---
 ---- Handler: closed stream 0 ---
 }}}
