Jason Rutherglen updated SOLR-1513:
-----------------------------------

    Attachment: google-collect-snapshot.jar
                SOLR-1513.patch

Here's a basic implementation, it needs testing for performance
and what happens if a value is removed before a key (in which
case the map could return null?). There are a number of
configurable params so we'll add those as options for solrconfig.

> ConcurrentHashMap is used in ConcurrentLRUCache.  The Google Colletions 
> concurrent map implementation allows for soft values that are great for 
> caches that potentially exceed the allocated heap.  Though I suppose Solr 
> caches usually don't use too much RAM?
