In only_wake_getmore_for_relevant_changes.js, a function called assertEventDoesNotWakeCursor is used to verify that a $changeStream getMore does not prematurely return if an unrelated change is written into the oplog. However, the getMore only waits for new data for 1 second, which makes this test sensitive to slow hosts. We should increase the duration of the getMores issued by assertEventDoesNotWakeCursor to perhaps 5 or 10 seconds.
