Y. Srinivas Ramakrishna	9ca97e4c78	7051430: CMS: ongoing CMS cycle should terminate abruptly to allow prompt JVM termination at exit It turns out that there is no need to explicitly stop CMS since the JVM is taken down at a terminal safepoint during which CMS threads are (terminally) inactive. This will need to be revised if and when we evolve in the future to a point where we allow JVM reincarnation in the same process, but those changes will be much more sweeping than just terminating CMS threads.
