> In order to make our efforts as generic as possible over in HBASE-1186, we need to add HeapSize functionality to more classes.
> This issue is so we have a central place to post code and discuss the issues related to determining the size of a Java object in memory.
> Erik Holstad and I have made good progress and have done significant research into other Java caching projects.  We will report our findings here.
