Y. Srinivas Ramakrishna	cf2163334f	6692906: CMS: parallel concurrent marking may be prone to hanging or stalling mutators for periods of time ... Inserted missing yield(check)s in closures used during the work-stealing phase of parallel concurrent marking, a missing synchronous yield-request in the cms perm gen allocation path, and a terminator-terminator for the offer_termination invocation that monitors the yield status of the concurrent marking task. Elaborated some documentation comments and made some task queue termination loop flags configurable at start-up to aid debugging in the field.

Y. Srinivas Ramakrishna	77f845359a	6948538: CMS: BOT walkers can fall into object allocation and initialization cracks ... GC workers now recognize an intermediate transient state of blocks which are allocated but have not yet completed initialization. blk_start() calls do not attempt to determine the size of a block in the transient state, rather waiting for the block to become initialized so that it is safe to query its size. Audited and ensured the order of initialization of object fields (klass, free bit and size) to respect block state transition protocol. Also included some new assertion checking code enabled in debug mode. Reviewed-by: chrisphi, johnc, poonam	2010-08-16 15:58:42 -07:00
