Under COLO, we are doing checkpoint on demand, if this
callback returns 1, we will take another checkpoint.
0 indicates unexpected error.
This doesn't seem to have a corresponding implementation. I think the
implementation ought to be in the same patch.
Surely, will merge it in the implement patch in next version
Thanks

If 0 is always an `unexpected error', perhaps the return value should
be an error code or something ? I'm not sure.
Ian.
