--------------------------------------
Thanks Lars, this looks better. Could you please address these two as well:
- Durability.java need InterfaceAudience annotations.
- Should we add some pointers in SYNC_WAL, and FSYNC_WAL javadocs to hflush,
hsync semantics? It might be confusing to first time comers.
> Allow a deferred sync option per Mutation.

> Won't have time for parent. But a deferred sync option on a per operation
> basis comes up quite frequently.
> In 0.96 this can be handled cleanly via protobufs and 0.94 we can have a
> special mutation attribute.
> For batch operation we'd take the safest sync option of any of the mutations.
> I.e. if there is at least one that wants to be flushed we'd sync the batch,
> if there's none of those but at least one that wants deferred flush we defer
> flush the batch, etc.
