While running G1 with 128g heap, I am observing # of regions close to 4k,
which is twice the target number of regions G1 tries to achieve (2048). I
would like to know any major reason/challenges for keeping the max region
size restricted to 32m, apart from what is mentioned in* src

Thanks and regards
