This new primitive doesn't allow stale reads, blocks readers when a write is pending or in progress, and enables writers to await completion of ongoing reads. The objective is to make the common-case (i.e. read path) as cheap as possible, preferably keeping bookkeeping local to reader threads and avoiding RMW instructions.
