--------------------------------------
Edward Epstein says in a note on uima-dev that the code for 1002 was probably
checked into the branch against UIMA-1019.
> Problem scaling out CAS multipliers
> -----------------------------------
>
> Key: UIMA-1002
> URL: https://issues.apache.org/jira/browse/UIMA-1002
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Reporter: Eddie Epstein
> Assignee: Jerry Cwiklik
>
> In order to avoid over filling request queues, all components in UIMA-AS that
> can generate new CASes to put into play are limited to a user definable
> value. CAS multipliers are limited by the size of their private casPool; when
> that is used up they must wait for CASes to be freed before creating new ones.
> Similarly, a remote CAS multiplier can generate and return as many new CASes
> as are defined for it's local CM casPool. At that point, it must wait for
> "free CAS" messages coming from it's client before sending more. Each remote
> CM uses a "free CAS queue" to receive these messages.
> Currently, all instances of a remote CM use the same free CAS queue. This
> must be changed so that every remote CM defines a unique free CAS queue.
