Bryan Duxbury updated HBASE-407:
--------------------------------

    Attachment: 407-v6.patch

This version contains a little test to show that SoftSortedMap actually 
decreases in size when there's memory usage. It probably needs to be varied by 
the heap size your system has.

> Client should cache region locations in an LRU structure
