If I use an async version of a call in a cluster ("ensemble") what happens if
the server I'm connected to goes down? Does ZK transparently resubmit the call
to the next server in the cluster and call my async callback or is there
something I need to do? The docs aren't clear on this and searching the archive
didn't give me the answer. Another source of confusion here is that the
non-async versions do not resubmit the call - I need to do that manually.Thanks!
