When running the web replay mochitests, the middleman (and, transitively, their child processes) are kept alive indefinitely per ContentParent::ShouldKeepProcessAlive. I think this is done so the content parents can be reused for new tabs, but we never reuse recording/replaying content parents. Avoiding keeping these parents alive, as this patch does, avoids test failures at shutdown that seem to result from these parents not shutting down quickly enough.
