I've found it very easy and efficient to do that sort of stuff with 'inotify'
where you can pretty much instantly call an application/script based on system
file-open/close/modify/read event and don't need to do any scanning. It only
works on files or directories though - not a hierarchical directory tree.

I think you would need to setup some file system notification thing to find
out if and when an xmp file changed. i have no idea how you would do that if dt
isn't running already. you would need to rescan all your xmp (several 10k for
me) at startup. unless there is a clever way to prune that (hierarchical
checksums with support in the file system..?) i think i'm not willing to pay
the performance penalty for this..
you can also re-read the xmp as soon as an image turns up in lighttable mode..
but that would not read new tags etc which potentially affect your collection.
so if you collect by a certain tag and load xmp on demand your lighttable view
might jump and keep adding/removing images.
