Handling graced objects between varnish servers.

I'm experimenting with a large varnish cache as a central master to  
multiple front-end caches.  The master having a long object grace and  
a slower LRU interval.  How long can I cache objects and keep them  
available as graced objects?  If a front end varnish cache receives an  
object from a downstream varnish cache that was served as a graced  
object will the front end varnish cache declare it invalid?  If so is  
there a way to bypass that invalidation?
