Summary: This test has been extremely flaky in the last few weeks, causing builds to not being released, or just sandcastle jobs failing randomly. The reason for the flakyness was due to the mtime stored in the dirstate being -1 instead of the real mtime of the file. The reason for the mtime to be -1 is to fix a race where a file is modified in the same second the dirstate is updated. This can happen when a transaction spans less than a second. By forcing a transaction to always last at least a second, we can avoid this issue and make the test stable.
