-------------------------------
Looking at recent 1.2 builds before this patch went in, it looks like the tests
cited above are already problematic:

https://builds.apache.org/view/H-L/view/HBase/job/HBase-1.2/151/jdk=latest1.7,label=Hadoop/consoleText

> We try to roll logs because can't append (See HDFS-8960) but we get stuck.
> See attached thread dump and associated log. What is interesting is that
> syncers are waiting to take syncs to run and at same time we want to flush so
> we are waiting on a safe point but there seems to be nothing in our ring
> buffer; did we go to roll log and not add safe point sync to clear out
> ringbuffer?
> Needs a bit of study. Try to reproduce.
