Allocator (currently defined only for Posix and Windows) using
munmap directly (or their Windows equivalents). There is no additional structure: each call to
allocate(s) issues a call to
mmap(null, s, PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANONYMOUS, -1, 0), and each call to
munmap(b.ptr, b.length). So
MmapAllocator is usually intended for allocating large chunks to be managed by fine-granular allocators.
The one shared instance.
Alignment is page-size and hardcoded to 4096 (even though on certain systems it could be larger).
