      The test jstests/core/max_time_ms.js fails when run in the linearizable readConcern override passthrough for the following test case:

      // maxTimeNeverTimeOut positive test for query.
assert.eq(1,
          t.getDB().adminCommand({configureFailPoint: "maxTimeNeverTimeOut", mode: "alwaysOn"}).ok);
t.drop();
t.insert([{}, {}, {}]);
cursor = t.find({
    $where: function() {
        sleep(100);
        return true;
    }
});
cursor.maxTimeMS(100);
assert.doesNotThrow(function() {
    cursor.itcount();
}, [], "expected query to trigger maxTimeNeverTimeOut fail point");
assert.eq(1, t.getDB().adminCommand({configureFailPoint: "maxTimeNeverTimeOut", mode: "off"}).ok);
