> In this thread http://mail-archives.apache.org/mod_mbox/zookeeper-user/201602.mbox/%3CCAPbqGzicBkLLyVDm7RFM20z0y3X1v1P-C9-1%3D%3D1DDqRDTzdOmQ%40mail.gmail.com%3E , I discussed an issue I've now seen in multiple environments:
> In a multi (using Curator), I write 2 new nodes. At some point, I issue 2 reads for these new nodes. In one read, I see one of the new nodes. In a subsequent read, I fail to see the other new node:
> 1. Starting state : { /foo = <does not exist>, /bar = <does not exist> }
> 2. In a multi, write: { /foo = A, /bar = B}
> 3. Read /foo as A
> 4. Read /bar as <does not exist> 
> #3 and #4 are issued 100% sequentially.
> It is not known at what point during #2, #3 starts.
> Note: the reads are getChildren() calls.
