That's only true for Windows 98/95/Windows 3.x and other DOS-based Windows versions. NTCreateProcess with SectionHandle=NULL creates a new process with a COW version of the parent process's address space. It's not called "fork", but it does the same thing. There's a new name for it in Win2K or XP (maybe CreateProcessEx?) but the functionality has been there since the NT 3.x days at least and is in all modern Windows versions. -- http://mail.python.org/mailman/listinfo/python-list
