The series is based on the localhost migration with side channel for ram series as it was already a good shape. But if you want to merge this first, I'll get rid of the migration part. I just tested page flipping migration, and tap/bridge-helper a bit, but have some environment problem on proxy fs driver. So it'd be appreciated if someone could help on verifying whether it has impact on it. :) Please let me know if there is anything needs to be improved. Thanks.
