Function std.experimental.allocator.building_blocks.ascending_page_allocator.SharedAscendingPageAllocator.deallocate

Decommit all physical memory associated with the buffer given as parameter, but keep the range of virtual addresses.

void deallocate (
  void[] b
) nothrow @nogc shared;

On POSIX systems deallocate calls mmap with `MAP_FIXED' a second time to decommit the memory. On Windows, it uses VirtualFree with MEM_DECOMMIT.
