Resumable clone

Hey, all,

A while ago, I noticed that if a clone is interrupted, it has to be restarted completely. When I looked up the issue, I saw that someone suggested resumable clones as a feature as early as 2007. It doesn't seem like any progress has been made on this issue, so I began looking at relevant code yesterday to start working on it.

Is someone working on this currently? Are there any things I should know moving forward? Is there a certain way I should break down/organize the feature when writing patches?

Any information is appreciated.

Thanks, Kevin
