Each of the last 5 failures has been accompanied by at least 25 other sync_integration_tests failing, e.g.:

TwoClientBookmarksSyncTest.SC_DeleteBMEmptyAccountAfterwards
TwoClientBookmarksSyncTest.SC_DelBMFoldWithParentAndChildrenBMsAndBMFolds
TwoClientBookmarksSyncTest.Sanity
TwoClientBookmarksSyncTest.SC_MovingBMsFromParentBMFoldToChildBMFold
TwoClientBookmarksSyncTest.SC_SinkBMs10LevelDown
TwoClientBookmarksSyncTest.SC_SetFaviconHiDPI
TwoClientBookmarksSyncTest.SC_TwiceRenamingBookmarkURL
TwoClientBookmarksSyncTest.SC_ReverseTheOrderOf10BMs
TwoClientBookmarksSyncTest.SC_DelBMNonEmptyAccountAfterwards
TwoClientBookmarksSyncTest.SC_DelFirstBMUnderBMFoldNonEmptyFoldAfterwards
TwoClientBookmarksSyncTest.SC_DelEmptyBMFoldNonEmptyAccountAfterwards
TwoClientBookmarksSyncTest.SC_ReverseTheOrderOfTwoBMs
TwoClientBookmarksSyncTest.SC_TwiceRenamingBookmarkName
TwoClientBookmarksSyncTest.SC_RenameBMName
TwoClientBookmarksSyncTest.SC_DelBMFoldWithBMsNonEmptyAccountAfterwards
MigrationTwoClientTest.MigratePrefsAndBookmarksThenModifyBookmark
TwoClientBookmarksSyncTest.SC_DelEmptyBMFoldEmptyAccountAfterwards
TwoClientBookmarksSyncTest.SC_UpdatingTitleDoesNotUpdateFaviconLastUpdatedTime
MigrationTwoClientTest.MigratePrefsThenModifyBookmark
TwoClientBookmarksSyncTest.SC_MovingBMsFromChildBMFoldToParentBMFold
TwoClientBookmarksSyncTest.SC_DelMiddleBMUnderBMFoldNonEmptyFoldAfterwards
TwoClientBookmarksSyncTest.SC_DelLastBMUnderBMFoldNonEmptyFoldAfterwards
TwoClientBookmarksSyncTest.SC_HoistBMs10LevelUp
TwoClientBookmarksSyncTest.SC_DelBMsUnderBMFoldEmptyFolderAfterwards
TwoClientBookmarksSyncTest.SC_RenameBMURL
TwoClientBookmarksSyncTest.SC_DelBMFoldWithBMsAndBMFoldsNonEmptyACAfterwards

So I'm inclined to think that it's not so much this test that is flaky, as a large chunk of the entire test suite.
