/* Implementation overview and caveats:
Win32 puts some contraints on what can and cannot be implemented. Where possible
we work around those contrainsts. Where we cannot work around the constraints we
either pretend to be conformant, or return an error code.

Some caveats: PROCESS_SHARED objects while they pretend to be process shared,
may not actually work. Some test cases are needed to determine win32's behaviour.
My suspicion is that the win32 handle needs to be opened with different flags for
proper operation.
