keeping a COM server alive

[Stefan Schukat]

Hi, 

there is no real solution if you are using a standard local server.
The server is as a COM object reference counted. So if the
reference count reaches 0 (no client) it will shutdown itself which
is done by design. If you want a different behavior you should write
either a service which exports COM objects and is started by the
operating system or a Python script which you start by hand, 
registers the class factories and then does not shut down.
