The PSM$REPORT routine reports to the print symbiont the
    completion status of an asynchronous operation initiated by a
    user routine.

    Such a user routine must return the completion status PSM$_
    PENDING. PSM$REPORT must be called exactly once for each time
    a user routine returns the status PSM$_PENDING.
