   $ hg status -C
 
+check that stat information such as mtime is preserved - it's unclear whether
+the `touch` and `stat` commands are portable, so we mimic them using python.
+Not all platforms support precision of even one-second granularity, so we allow
+a rather generous fudge factor here; 1234567890 is 2009, and the primary thing
+we care about is that it's not the machine's current time; hopefully it's 
really
+unlikely for a machine to have such a broken clock that this test fails. :)
+
+  $ mkdir mtime
+Create the file (as empty), then update its mtime and atime to be 1234567890.
