I can't do much to check it now. I do not have time to setup the
required environment on my new pc now.

However I think it is also very difficult to catch such errors. They
are likely to be race conditions (since w32 messages from different
sources are involved).

So I think it is better to check the logic. (As I have tried to above.)

And I also still think it is a good idea to add check for error
conditions after all system calls. (For the same reason as above.)
