Perhaps my proposal for a modification-sensing serial number could be
extended to work on all files as long as they're open?
Summary:
- New files created in "Modified" state.
- Reading serial number changes file to "Not-Modified".
- Modifying file sets "Modified" state -- and if previous state
was "Not-Modified", increments serial number once.
- "Not-Modifed"->"Modified" transition propagates to parent
- directory.
