Subject: COW pages and paging question

Hi,

when a process forks it's pages become shared by COW. Now one or both 
processes are written partially to the swap space. Later some pages are paged 
in.

Are they still shared between the 2 processes? (Assuming they are not written 
to and cover the same address range)

Thanks,
Torsten
