NoSQL databases, now 'ACID' compliant?

A well-known problem with NoSQL databases in general is that they do not support the 'ACID' principals held dear by traditional RDBMS DBAs. The Register is reporting that this may soon change with FoundationDB. Atomicity ensures that a transaction is saved or undone, but never exists halfway between the two states. Consistency ensures that only valid data can be stored. Isolation of transactions prevents one transaction interfering with another. Finally, durability ensures that transactions committed will endure and be protected from loss.
