Here's another approach: have FSDirectory.renameFile() call 
File.setLastModified() on its directory.  It doesn't need to check what 
OS is running--this always a correct thing to do.

Then we can just use the directory's modified time to see when the index 
has changed, keeping that operation fast and cheap.
