Subject Re: pzxid field in stat structure
Date Tue, 18 Oct 2011 17:32:27 GMT
Good question. 

One thought is that you can use the multi for this except that I don't know if the parent
version changes when adding or removing a child.  On the other hand you could also update
the content of the parent in the same multi to free the version update.
