New issue 3976 by [email protected]: OOM crash caused by GC not keeping up with fragmentation
https://code.google.com/p/v8/issues/detail?id=3976

I attached a test that causes OOM in V8 even though only 14% of the heap is used.

[29775] 3107 ms: Mark-sweep 1412.7 (1456.6) -> 163.5 (1028.6) MB, 249.3 ms [allocation failure] [GC in old space requested]. [29775] 3878 ms: Mark-sweep 626.3 (1456.6) -> 194.4 (1456.6) MB, 242.8 ms [allocation failure] [GC in old space requested]. [29775] 4168 ms: Mark-sweep 230.0 (1456.6) -> 194.4 (1456.6) MB, 241.8 ms [last resort gc]. [29775] 4474 ms: Mark-sweep 194.4 (1456.6) -> 194.4 (1456.6) MB, 305.7 ms [last resort gc].
