> We are currently executing unnecessary puts into the message store on the primary execution path of message routing.
> When a new message arrives - it is first added to the message store. The message is only ever retrieved from the message store if a reference is loaded from paging and we want to make sure we do not have more than once instance in memory at once.
> The first put is therefore unnecessary and will have some performance implications. Also message store is currently a synchronization bottleneck so this should aid concurrency. Messages should only be added to the message store (if necessary) when they are paged to storage
