So it is stable now?

[Yisaer]

I tested this case 100 times by test.count 100 and the results is fine. I guess it's stable now.

[wjhuang2016]

So much sleep in this test, I guess that's why it's unstable?

good catch, I think the root cause of the unstable test might be caused by test dynamic timestamp stale select when meeting cpu resource shortage. I removed these testcases for now. @xhebox WDYT?

[xhebox]

makes sense, dynamic timestamp test is much strict than other tests.
