Fix a noisy unit test.
Fix a noisy unit test.

Summary: The t/DBTest.DropWrites test still fails under certain gcc version in release unit test.

I unfortunately cannot repro the failure (since the compilers have mapped library which I am not able to map to correctly). I am suspecting the clock skew.

Test Plan: Run make check
