Could you please rephrase this.

This should be part of patch 1 as this patch is all about the wrapper 
and its usage.

Same here.

Same here. (And in multiple other places)

Please move anything not dealing with the wrapper to the first patch or 
even a separate patch if you find that more appropriate.

Do not call '_create_lease' from anywhere outside 'create_lease'. 
Otherwise the wrapper doesn't add any value.

Also, please ensure that we've results for kms_lease on patchwork.
