CMS collection keep working during holiday

[Ken--@newsgroupstats.hk]

Follow up to the jconsole above. This gif is captured today. You can see the
first CMS after a FULL GC is working. The 2nd one is working too but the
memory free from 2nd generation is much less than the first CMS. The memory
free by 3rd CMS is further decreased.

The 5th CMS cannot free enough memory to make occanpcy in old-gen to less
than 70%. So, continue non-stopping CMS happen again until a Full GC
(triggered by Concurrent Mode Failure).
