Q. The maximum number of entries in the
_cluster space is 32. Tuples for out-of-date replicas are not automatically re-used, so if this 32-replica limit is reached, users may have to reorganize the
_cluster space manually. Is this restriction still there? (2016)
A. Yes. We're working on reuse in 1.7, it will be LRU-based, but the restriction is still there.
