Issue #18. When restore fails ghost files remain there. And to remove them we have to know their list, paths to original files (to construct the ghost name) and the namespace ghost lives in. For the latter we keep the restore task namespace at hands till the final stage and setns into it to kill ghosts. Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
