      1) Setup a config server, a mongos and 3 replicaset members.

      2) Run the primary node in a shell and in foreground (without --fork).

      3) Run attached rstest.sh to create an insert load via mongos to the primary.

      4) Stop the primary node with Ctrl-Z.

      5) Wait forever

      6) Notice that rstest.sh is stuck and not inserting anything anymore, even if a new primary is available and known to mongos.

      7) press Ctrl-C in the rstest.sh shell. (twice)

      I didn't see a separate project for the shell, so continuing to send this to core server. Please reroute as needed.

      I believe this is the shell getting stuck, but could potentially be mongos too.

      Bug: When primary node stops (Ctrl-Z) during a query, client (the shell) will wait forever.

      Proposed fix: Client should timeout and error out.
