Thinking about it, there might be a possibility to address it (at least on
Linux) using fanotify. Not sure about other platforms but maybe there are
some solutions to address it. Also it might get a bit complex and not sure
how much the solution is viable.
I guess we should first research and maybe PoC to which extend this can be
actually fixed. I will try to prioritize it and look into it in the coming
weeks.
