This isn't going to work. It needs to be modified in a few ways:

1. It should use async APIs.
2. There should be an included test.
3. What is the default behavior on Windows or Posix? There should be a flag added to control this behavior.

I really appreciate your interest and willingness to help. If you can't or don't want to make these modifications now, not a big deal. I will get to it eventually :)

Of course, you are right about this :-)

After a few hours of searching our actual problem, we did not think enough about how to do it properly. Sorry for that.

Unfortunately, to make it right, at least right now we do not have the time ... sorry :-(

I figured, that's OK. I'll leave this PR open as a reminder for myself :)

This PR can then be closed, as it has been superseded by #141.
