Yes, I agree - see my other post :)  I just didn't think it through enough
at the time - I recently stuck a sys.isapidllhandle in a new py2exe
extension, and sys.frozendllhandle has existed for some time.  I just had
sys on the mind :)

I think a simple attribute should be OK - no need for a function call.  As I
implied in my other mail, a simple way of knowing if you are being run for
debugging may also help - at the moment you would need to imply that if
is_service is False, you are being debugged - but that isn't necessarily
true.
