I'm planning to have a go at this.  Will post some thoughts later.

> Use case in HBase is that we need to recursively delete multiple subtrees:
> {code}
>     ZKUtil.deleteChildrenRecursively(watcher, acquiredZnode);
>     ZKUtil.deleteChildrenRecursively(watcher, reachedZnode);
>     ZKUtil.deleteChildrenRecursively(watcher, abortZnode);
> {code}
> To achieve high consistency, it is desirable to use multi for the above operations.
> This JIRA adds support for recursive deletion in multi.
