Playing w/ OOMERegionServer, need to do some more work in HRS around OOME:

> [hbase] OOME makes zombie of region server

> Key: HADOOP-1813
> URL: https://issues.apache.org/jira/browse/HADOOP-1813
> Project: Hadoop
> Issue Type: Bug
> Components: contrib/hbase
> Reporter: stack
> Assignee: stack
> Priority: Minor
> Attachments: failed_compaction.log, oome.patch

> We need to catch Errors in the main regionserver and master run methods.
> During a cluster loading, an OOME made main thread exit but server stayed up
> doing a zombie-impersonation. For OOME's we could add an attempted handler.
> Service threads also need to be 'daemon'-ified. Here's an extract from
> thread dump of hung region server:
