- Under Linux, the number does not change when you move/rename the file 
(though apparently when you remount the filesystem).
- tla can tolerate inode changes in working directories.  There are 
plenty of unix operations that change inodes, like "cp foo bar; rm foo; 
mv bar foo".  I have worked on the changeset code recently.  It is robust.
- Changes in revlibs or pristines after inode signatures have been 
snapped would be problematic, but I'm not sure whether they happen.  
Does a file's inode change when its parent directory is renamed?  When 
the box is rebooted?
