-----------------------------------------+-------------------------
As originally noted at comment:7:ticket:33211, the quic-go turbotunnel
client sometimes uses 100+% CPU for a few minutes before returning to
normal operation. It is specific to the quic-go implementation; it doesn't
happen with the kcp-go implementation nor the non-turbotunnel client.
As best I can figure, the cause has something to do with timers created
under `(*session) maybeResetTimer`.
