+Some filesystems (notably FAT/exFAT only store timestamps with 2
+seconds of precision, so by sleeping for 3 seconds, we can ensure that
+the timestamps of files stored by dirstate will appear older than the
+dirstate file, and therefore we'll be able to get stable output from
+debugdirstate. If we don't do this, the test can be slightly flaky.
