Let me add Eric to the "To:" line for visibility. And see if he has experienced this during his development of it. I've not looked at the inotify code so I can't say if there are races there or not. Tests that move directories feel like good candidates for race conditions -- since the daemon doesn't get a recursive view of the tree with inotify() and must simulate that and manage the individual directories, but again I don't want to assume that.
