> The L1TxInterceptor currently doesn't block on L1 invalidations during a 1PC.  This can cause an inconsistent view of data across non owner nodes.
> Example:
> {quote}
> Node A owns k with value of v1
> Node B has k in L1 with value of v1
> tx1 started
> Node A put k -> v2
> Node A sends invalidation
> Node A commits
> tx1 completed
> tx2 started
> Node B get k returns v1 from L1
> tx2 completed
> Node B gets invalidation for k
> tx3 started
> Node B get k remotely retrieves v2 from Node A
> tx3 completed
> {quote}
> We need to make sure that all L1 invalidations in Tx mode are completed before completing the transaction.
