In general and to be completely safe I would agree (generally a bad
practice, but who wants to use C++ if it can be avoided).
However if objects are created in the same apartment and same thread with an
Inprocess DLL only, I have always found them to be in the same
process/thread space. Actually from the way I see this, this must always be
okay - as long as the COM objects reside in the same DLL and same apartment,
as the is nothing special in Delphi terms about the
TAutoObjectFactory.CreateComObject call.
For out of process or local servers this would always fail.
