    Don - question, accepting completely the NOTIFY locks used by ADS across
    pseudo-converse. Here's a scenario.

    1) The dialog does OBTAIN on record types A, B and C, and a MODIFY of C in
    the premap. At the pseudo-converse the update of C must be COMMITTED when
    the FINISH of the run unit occurs - but ADS maintains NOTIFY locks on the 3
    record types.

    2) Now - in the response process the dialog does an OBTAIN and MODIFY of
    record type D - when ADS BINDs the Run Unit would it not re-acquire the
    NOTIFY locks as database run unit locks PRIOR to doing the OBTAIN and MODIFY
    of record type D?

    3) So it would be possible for the A, B or C record types to interact with
    other active tasks - thus causing confusion for the developer who only sees
    record type D referenced in the response process code?

    Just curious - as this is the sort of scenario that I believe the CAS user
    is seeing.
