Actually you might want to tenure them "early": if your oldgen is  
collected concurrently _and_ the young collection frequency is larger than  
a typical transaction (which is a fairly common situation).

Therefore there is an argument for using MaxTenuring=0 (or only 1). But  
thats not really G1 related, I just wanted to mention it.
