130 In this case, an anonymous, unnamed shared memory object is created.
137 the shared memory object will be garbage collected when the last reference to
138 the shared memory object is removed.
139 The shared memory object may be shared with other processes by sharing the
144 Attempting to open an anonymous shared memory object with
158 object is always backed by aligned, physically contiguous chunks of memory.
170 Largepage shared memory objects behave slightly differently from non-largepage
174 Memory for a largepage object is allocated when the object is

219 If the (non-blocking) memory allocation fails because there is insufficient free
220 contiguous memory, the kernel will attempt to defragment physical memory and
