    Does anyone know - in WinNT4 and / versus Win2k - how the division of
    COM / DCOM / RPC labor is distributed between ring 0 and ring 3 ?

    Is this documented anywhere?

    I've been experimenting with ::GlobalMemoryStatusEx and the
    MEMORYSTATUSEX.dwMemoryLoad value as an adaptive means to protect a long
    running NT service from potentially getting itself into a low memory
    situation (please excuse the fractured pseudo code):

            if ( MEMORYSTATUS.dwMemoryLoad >= 95 )
                    {
                    err.description = "request refused - try again later -
    system is low on memory right now ;-)";
                    return E_FAIL;
                    }

    TIA,
