Not only that: by definition, every process that writes to the 
filesystem will send this signalling system into an infinite loop!

Yes, you could prevent that by not notifying the process that canged the 
file - further slowing down the system with more checks ;-)

Oh and - in order to implement this efficiently, every process would 
need to have the signalling code embedded, since making it a system call 
would mean.. even more slowdown !

The list goes on...
