> We need to handle long-lived requests to support replication. To make this work we need to make the processing mechanism asynchronous from the network threads.
> To accomplish this we will retain the existing pool of network threads but add a new pool of request handling threads. These will do all the disk I/O. There will be a queue mechanism to transfer requests to and from this secondary pool.
