Hi Jason,

thanks for the input. Sorry for the long response lag. I'm very short
of time at the moment. The current project of my firm is in a critical
state, so I don't see the daylight as often as I want :(

I agree to your text. I know, that my model isn't really complete.
Did you read my description? Did you test one of the latest
snapshots with CYGWIN=ntsec? I'd like to hear your opinion.

Shame on me: I didn't read the aforementioned tech note so far.
Would you be so kind, to send it as an attachment, so I can't forget
it to read?

I would appreciate further discussions but please be patient.

Best Regards,
Corinna
