3) This is just a question I have.

On half of Guru Prasad <guru_bn@yahoo.com>,

3) This is just a question I have. What happens when we have an
application that takes checkpoint on its own and also Grid-CPR is
checkpointing it. This may result in redundancy of meta data and wastage
of CPU cycles. This sort of ties to Data Integrity in my previous
comment. But we have to be able to recognize such applications and make
a decision to checkpoint or not to checkpoint.

Re: 3) This is just a question I have.

Do you have a particular Use-Case in mind where detecting and resolving conflicts between multiple checkpointing systems
 is a requirement? If so, could you please write it up and submit it to the list.

Thanks for your comment.

Proposal: issue should not be addressed, as its of no explicit concern in the current scope of the document.  The data 
integrity issue is addressed (see other comments).

Re: 3) This is just a question I have.

Discussed on call:
 - confusion of system level and app level checkpoint
 - keep text as is, as it makes clear that GridCPR is app. level checkpointing.
 - possibly add a sentence in introduction on what "GridCPR is not".
