When a transaction with N_LOCKTIME>0 is created, does that transaction get stored in a block on the blockchain or is it stored in the mempool until the actual time (or block number) exceeds the current value?  If it is stored on the blockchain, how does that affect the concept of pruning that is supposed to be going in to version 0.11?  I.e. if I create a transaction that doesn't take effect for 10 years, and that transaction is stored in a block, does that block stay on the active list for that period of time?

Thanks,
