--------------------------------------

Opened new JIRA as HBASE-729. 

Regarding this issue, JB -- Did your client actually die with an OOME, or were you speaking
hypothetically?

> cachedRegionLocation stores region locations of tables whenever new region is looked
up. However, the enties are deleted only when TableServers object is closed or locateRegion
is called with false useCache argument. Therefore, it seems to grow without limit and cause
out of memory exception.
