There is no reason for that guarantee, and it is not explicitly the purpose of these tests, so let's make the checking more intelligent and flexible. child_start and child_exit events share a child ID - using that child ID, we can try to disambiguate which child_exit belongs to which child_start and limit our validation to only the pager's child process.
