Turning off generational GC

[Jon Masamitsu]

For the hotspot garbage collectors the short answer is "no" there is no 
way to
turn off generational GC.  I think it's even pretty deeply entrenched in 
G1 which
is only logically generational.

If CMS were not generational, in the best cause you would see pauses
on the order of 20ms.  Maybe much larger although less frequent.
More likely would be concurrent mode failures which would lead to
full GC's.
