Very interesting.

Ok, so the facts are:

- hg 1.0.1
- Linux
- NFS
- Mysterious multi-repo extension

There are a couple known windows where dirstate can get out of line:

- edits during commit
- edits during checkout
- possibly edits during status

The last is because we opportunistically update the dirstate for files
that we determine are clean.

Also, there are a couple extensions that have been known to cause status
issues in the past:

- keyword
- inotify
- win32text
