Re: large heaps

Hey Nicolas, I've corresponded with that guy a few times in the past -- back when i was attempting to hack some patches into G1 for better performance on HBase. The end result of that investigation was the MSLAB feature which made it into 0.90.x. The main thing I learned about GC is that big heap
