58If set, the kernel will force sharing of the entire address space,
59typically by sharing the hardware page table directly.
60The child
61will thus inherit and share all the segments the parent process owns,
62whether they are normally shareable or not.
63The stack segment is
64not split (both the parent and child return on the same stack) and thus
