 LOCATED BY : Dependent on the function; registers in
              HCPIDS
 CREATED BY : HCPEXD when setting up for a local send
 DELETED BY : HCPEXD when handling a message complete
              interruption
              HCPEXD when cleaning up after a failed send
 SERIALIZED : Task ownership
 RELOCATION CONSIDERATIONS : None
 COMMENTS   : None
