Yes, but we only need the last change. So we could record the "last 
time" it changed and reload it as soon as its more than one second ago.

We could just use two timers... one that regularly checks if mtime 
changed. If it changed, we start a second timer with a delay of 1 
second, which reloads the file.

The HNAs are only sent every 5-60 seconds anyway, so there is no need to
