I would have thought that this "limit" could be  regarded as indefinite as 
far as cryonics is concerned. If someone remains  cryopreserved for any 

appreciable fraction of a million years this tends to  suggest that reanimation 
is 
becoming increasingly unlikely as time moves  on.



John:
 
Permafrost is rather warmer than liquid nitrogen, so if DNA and even  

bacteria last a million years in permafrost then it, they and we should last  
forever 
at -195C. As you say, if we haven't been revived in a million years we  

probably never will be, though I prefer to think this datum shows there will be
"plenty of time to learn to revive us." Even if it takes forever.
