> If we execute a request with paging turned off, an IN restriction on the partition key,
ORDER BY and LIMIT the result returned are not the expected ones.
> The following test can be used to reproduce the problem.
> {code}
>         createTable("CREATE TABLE %s (pk1 int, pk2 int, c int, v text, PRIMARY KEY ((pk1,
pk2), c) )");
>         execute("INSERT INTO %s (pk1, pk2, c, v) VALUES (?, ?, ?, ?)", 1, 1, 2, "A");
>         execute("INSERT INTO %s (pk1, pk2, c, v) VALUES (?, ?, ?, ?)", 1, 2, 1, "B");
>         execute("INSERT INTO %s (pk1, pk2, c, v) VALUES (?, ?, ?, ?)", 1, 3, 3, "C");
>         execute("INSERT INTO %s (pk1, pk2, c, v) VALUES (?, ?, ?, ?)", 1, 1, 4, "D");
>         assertRows(execute("SELECT v as c FROM %s where pk1 = ? AND pk2 IN (?, ?) ORDER
BY c; ", 1, 1, 2),
>                    row("B"),
>                    row("A"),
>                    row("D"));
>         assertRows(execute("SELECT v as c FROM %s where pk1 = ? AND pk2 IN (?, ?) ORDER
BY c LIMIT 2; ", 1, 1, 2),
>                    row("B"),
>                    row("A"));
> {code}
