Yes. There is not guarantee that the client isn't using a given page. More importantly though, it just doesn't make sense to change an executable dynamically. How would you make the transition from one executable code to the other seamless?

That won't stop your processes from crashing when you delete the file from underneath them, but it is indeed the recommended way to handle this sort of problem. This is the way programs such as 'install' (a.k.a. ginstall) work.
