> To mitigate this, tuple spaces may use locking or transactional mechanisms to ensure consistency and prevent conflicts.

I think I played with some kind of TupleSpace implementation around 2009 or so (as part of a "paradigms of distributed systems" course) and I'm pretty sure it was some kind of hybrid STM (software-transactional memory) / TupleSpace thing that addressed that issue. It was pretty cool... again from vague memories here, I believe it only had tuple-level locking, but you could build a bunch of really neat higher-order synchronization primitives on top of just tuple-level locks.
