This description makes sense. From my understanding of signals, the code also does make sense, but it is unfortunate that it has to be so much code to implement something as straight-forward as suspend/resume. FWIW I tested the `add -p` command with these patches on Windows and it still works as well as when I had developed it. Thank you, Dscho
