New issue 1682 by [email protected]: NewGC: use collected live bytes
counts instead of naive heap size estimation after full collection
http://code.google.com/p/v8/issues/detail?id=1682
Lazy sweeping makes naive heap size estimation unreliable.
In turn "fake" heap size makes all our heuristics highly imprecise (e.g.
old generation limit and old promotion limit are set too high).
We should also output live bytes counts collected during marking in
--trace-gc otherwise there is an illusion that full collection freed only
little memory.
