> It may be a bug in the constructor of SharedMemory. It ignores > the size argument on Windows. The `size` argument is always ignored when `create` is false, on all platforms, not that I understand the reason for it. The difference compared to POSIX is that the size of a mapping that's backed by the paging file is rounded up to a multiple of the page size in Windows (e.g. 4 KiB).
