6782457: CMS: Livelock in CompactibleFreeListSpace::block_size()
6736295: SIGSEGV in product jvm, assertion "these are the only valid states during a \
                mark sweep" in fastdebug

"safepoint-blocking" on locks, in this case the Heap_lock, while holding \
                uninitialized allocated heap storage.
