> {A,B,C, D}, num owners= 2. A's state is {(k,v)} and a transactions is prepared with {(k, otherValue)} on A.
> B crashes.
> two things happen with A's state: 
> 1. on C an thread pulls state from A
> 2. A sends transaction state to C on another thread
> Whit the right timing:
> - 2 executes first (tx log is drained)
> - tx commits - this applies the changes on C as well 
> - 1 executes last 
> Data ends up inconsistent:
> A's states is {(k, otherValue)} while C's state is  {(k,v)} 
> State transfer and tx log needs to be sequential (not parallel).
> See the attached email thread for discussions around this.
