degradation when there are a lot of subscribers

   We are going through so many scholar back and forths.. and I'm lost now...
   
   I don't understand why we need two page caches now.. one on softCache, one 
on indexCacheMap
   
   The idea of the softCache was to let PageCache go, and be reconstructed if 
memory is really low.
   
   
   If you are adding a permanent cache, why not remove the soft Cache? Why do 
you intend to break the soft references here?
   
   
   A SoftCache is only released if memory is really low.. so why break that 
rule?
