I don't think Ioannis was speaking about shared server case here. I think
he says that in a simple FUSE remote notification setup we can loose OPEN
events (or basically any other) if the inode for which the event happens
gets deleted sufficiently early after the event being generated. That seems
indeed somewhat unexpected and could be confusing if it happens e.g. for
some directory operations.
