Thanks Dag!

So, my normal routine of manually restarting Apache after PHP updates is 
a good one to follow.

I do think though that this could be considered a bit of a hole. With 
automatic updates being pushed to the forefront... where updates might 
happen when you're not even at the machine.. one could easily miss this 
sort of thing. And, as many of my systems run at least as long as it 
becomes necessary to reboot due to a kernel issue that actually effects 
something I'm running... it could be a long time between an update and a 
service restart. This is sort of frustrating to some degree.

Now to figure out what might need to be restarted based on what is 
updated each time.. not such an easy task anymore with the huge number 
of packages and the interrelationships between those packages. Hmmmmm....
