The thing about shared memory is it's just that. It's shared. You still
have to know to see whether something has changed.

Once you know something _has_ changed, of course, then it's not a
problem - shared memory is an efficient way of getting large chunks of
data from one executable to another. It's just that it's a horribly bad
way of sending a message in the first place, because your code would
have to sit in a loop looking for the change.

Basically, you need another way to communicate first.
WaitForSingleObject is one way.
