Subject: [PATCH] DBTest.HardLimit made more deterministic

Summary: In DBTest.HardLimit, multiple flushes may merge into one, based on thread scheduling. Avoid it by waiting each flush to finish before generating the next one.

Test Plan: Run test in parallel several times and see it doesn't fail any more.
