> It looks like there's another value for `KeepAliveTimeout` in the
[https://github.com/xtaci/smux/blob/v1.5.12/mux.go#L45 defaultConfig] and
the session will close itself if it hasn't received any data during this
timeout
[https://github.com/xtaci/smux/blob/c6969d8a76874342611f4b544d05b1590f1a76b1/session.go#L393
here]. This defaults to 30 seconds (which is the same as our current check
for staleness).
We override `KeepAliveTimeout` to 10 minutes
[https://gitweb.torproject.org/pluggable-
transports/snowflake.git/tree/client/lib/snowflake.go?id=7043a055f9fb0680281ecffd7d458a43f2ce65b5#n83
here (client)] and [https://gitweb.torproject.org/pluggable-
transports/snowflake.git/tree/server/server.go?id=7043a055f9fb0680281ecffd7d458a43f2ce65b5#n303
here (server)]. If 10 minutes expire, it does indeed kill your session and
close the SOCKS connection, but it takes many proxy failures in a row for
that to happen.
