+The way we solve this is by doing versioning as an acyclic directed graph of PDUs. For backfilling purposes, this is done on a per context basis. 
 When we send a PDU we include all PDUs that have been received for that context that hasn't been subsequently listed in a later PDU. The trivial case is a simple list of PDUs, e.g. A <- B <- C. However, if two servers send out a PDU at the same to, both B and C would point at A - a later PDU would then list both B and C.
 
 Problems with opaque version strings:
     - How do you do clustering without mandating that a cluster can only have one transaction in flight to a given remote home server at a time. 
-      If you have multiple transactions sent at once, then you might drop one transaction, receive anotherwith a version that is later than the dropped transaction and which point ARGH WE LOST A TRANSACTION.
