Detailed Description

Active receive broker that keeps a pool of pre-posted Irecv slots per size-class tag to drain unexpected ActiveMsg traffic quickly.

Each completed slot dispatches directly to finishPendingActiveMsgAsyncRecv and is immediately reposted with a fresh buffer of the same capacity.
