Ahh, I find it a little confusing that ShouldResume() calls WillResume().
ShouldResume() to me sounds like a function that should be const. It seems
like it should just ask a question and gets a yes/no answer, but not modify
But looking over the code, it looks like WillResume() actually means "I
don't know if you need to resume or not, but if you do, then do it, and if
you don't, then tell me that by returning false"
