FWIW, I rebuilt all of kde (well, the packages with the option) without 
semantic-desktop at all, here on gentoo, shortly after 4.7.0 came out, 
when I removed all kdepim components and akonadi, and thus could do so.  
So all that stuff's not only diabled so it doesn't run, it's build-time 
disabled and thus not installed at all, on my system! =:^)

However, based on the changelogs for 4.7 and the continued improvements 
in 4.7.3, I believe once it's done indexing (or checking that its index 
is still current after the initial indexing), it now turns on fanotify or 
whatever similar kernel-level filesystem monitoring, and thus knows when 
a file changes so it can reindex it.

... Assuming the required kernel config option is enabled in the kernel 
you're running, of course.
