> During node crash, two concurrent modifications in can both succeed in pessimistic tx cache.
> This also causes random failures in {{InfinispanNodeFailureTest}}:
> 1. TX1 originating on A acquires lock for key X, A is primary owner
> 2. C is killed and B becomes primary owner of key X
> 3. TX2 originating on B acquires lock for key X, B is now primary owner
> 4. TX1 commits the tx, Prepare is sent with the new topology id so it commits fine
> 5. TX2 also commits the transaction
> Log attached (this is not master but changes should not be related).
