|
* We will have a number of different strains.
|

|
|
*
|
||
|
|
* (1) p3Service -> pqiService
|
||
|
|
*
|
||
|
|
* Basic service with serialisation handled by a RsSerialiser.
|
||
|
|
*
|
||
|
|
* (2) p3ThreadedService -> p3service.
|
||
|
|
*
|
||
|
|
* Independent thread with mutex locks for i/o Queues.
|
||
|
|
* ideal for games etc.
|
||
|
|
*
|
||
|
|
* (3) p3CacheService -> p3service + CacheSource + CacheStore.
|
||
|
|
*
|
||
|
|
* For both Cached and Messages.
