rev 3631 : 7188263: G1: Excessive c_heap (malloc) consumption Summary: G1 was allocating the global marking stack and some per-worker marking data structures from C heap, resulting in approximately 7Mb being allocated for each marking thread. Reduce the pressure on the C heap by allocating some of these marking structures from virtual memory instead. Reviewed-by:99 lines changed: 79 ins; 6 del; 14 mod; 4408 unchg
