I've reviewed the patchset, have some minor comments, but overall it
looks good.  The changes are contained, and common code / existing
code paths are not affected much.  We can still target to merge this
for 2.8.

Do you have any tests on how much the VM slows down / downtime
incurred during checkpoints?

Also, can you tell how did you arrive at the default checkpoint
interval?

Thanks,

                Amit
