Pipe through exit statuses in AOS Run() methods
This makes it so that the sundry Run() methods can return exit statuses
when exited using the ExitHandle. This enables certain categories of
error-handling that were hard to do previously---in particular, this
enables future modifications to LogReader to propagate log reading
faults through this interface.
