> Beeline adds a bad connection(s) to the connection list and makes it the current connection,
so any subsequent queries will attempt to use this bad connection and will fail. Even a "!close"
would not work.
> 1) all queries fail unless !go is used.
> 2) !closeall cannot close the active connections either.
> 3) !exit will exit while attempting to establish these inactive connections without closing
the active connections. So this could hold up server side resources.
