> If the containizer launch path fails before actually
> launching the container, the FDs allocated to the container by the
> IOSwitchboard isolator are leaked. This leads to deadlock in
> the destroy path because the IOSwitchboard does not shutdown until the
> FDs it allocates to the container have been closed. Since the
> switchboard doesn't shutdown, the future returned by its 'cleanup()'
> function is never satisfied. 
> We need a general purpose method for closing the IOSwitchboard FDs when failing in the
launch path.
