That sounds fine - thanks to you and to Goffredo!

I've just run the first test - finding reliable (for only this case)  
messages is a bad job ...

There's some problem in the Wiki. This new paragraph (?) is not shown  
when I call the "Problem_FAQ", it ends with the "Copy-on-write doesn't  
work" question.

When I look into the source code of that page I can see and read the  
paragraph, and it looks fine!

Viele Gruesse!
