3.2.1.2.6 Host Calls CI Table
The server MUST maintain a table associating an integer identifier with outstanding RUNSPACEPOOL_HOST_CALL messages (section 2.2.2.15) originating from the higher-layer.
The table is used to map the server requests to corresponding client responses with the "ci" property of RUNSPACEPOOL_HOST_RESPONSE messages (see section 2.2.2.16).
