Kernel, libc: Implement fork() This time for real. Also, add a new per-user-task virtual address allocator (UserHeap), so that mmap'ed pages are in user range and can be copied. 2022-10-17 16:43:35 +00:00			`void clear();`

Prepare for cloning address spaces, not there yet 2022-10-14 16:17:57 +00:00			`AddressSpace clone();`
It (almost) works now The only thing doing weird stuff is exec(), so that's commented out and throws ENOSYS right now. But we have two user tasks running in parallel, isolated from each other! 2022-10-14 14:46:00 +00:00
