Just a quick sanity check. Why won't the change get noticed? Any file
writes should be seen by the inotify code which would invalidate the
cache? This could mean we're not watching some dependency we should be?
or is it that the commands aren't triggering a reparse due to ordering
somehow? I'd like to understand this more before we add this...

Cheers,
