This has been a known bug, though it is still good to bring it up. If
you "touch" the file, it will show up as modified again.

The problem is that chmod does not update one of the timestamps that tla
uses to detect modification. Since that hasn't been changed, tla does
not look further to see if any of the meta data has been modified.

I *think* the simple fix is to just have the mode of the file be part of
the inode signature.
