I guess you're right Andrey and it was just merely a delay in Windows,
because the link/file-counter seem to be 0 and it was just an observable
defect but not an practical defect (once I tested it in other ways, i.e.
fopen etc didn't act as it existed)


I'll come back if I encounter any practical/programatic problems with it

I'm sorry for not testing it properly before I did this "report"


Kristian
