Currently, the launchd service is blocked with probability in the WebContent process. This patch blocks it in all cases
with a new enablement flag. Having blocked for 1-2 weeks with probability, we haven't found any failures. So now we believe
it's safe (or at least, as safe as it will ever be within the limits of our current development process) to block in all
cases.
