Detailed Description

Buffers messages until record is replaced in the hash table, then delivers all messages to the replacing record.

This is used when a message arrives for a local element that has not yet been created, buffering messages until the new element finally checks in.

It's silly to send a message to an element you won't ever create, so this kind of record causes an abort "Stale array manager message!" if it's left undelivered too long.
