      establishCursors() has a best effort try-catch-throw block here. However, our underlying pattern for the ARS is prone to throwing after interruption. We should introduce a separate draining pattern for the ARS and use it from establishCursors().

      This is usually a seen as an invariant in this block in mongo/transport/baton_asio_linux.h:

      Invariant failure _scheduled.empty() src/mongo/transport/baton_asio_linux.h 116
