Revise FUSE-client to call p4 reconcile intelligently.
This uses the main FUSE callbacks like a loopback with a notification mechanism. After no real disk access after a short period of time (like 500ms) we'll trigger a call to p4 reconcile.
The "interface" to this application is currently just a file handle:
/.status - Lists "ok" if there's no errors, otherwise, outputs a list of messages
