 Description   

This test relies on failpoints to simulate an advantageously hedged read request. However, based on this BF-19852, the test setup still does not guarantee that the response for the original request always arrives after the response for the hedged/additional request does. The quick fix to increase the blockTimeMS for the original request. However, unless we use a large blockTimeMS, there is a non-zero chance that we get a similar BF in the future. So we might need to rewrite this test to not rely on failpoints.
