The downside of that approach is that you have to
busy-wait on that flag, while the pipe approach allows
the application to be completely idle (and still have
fast response to the signal)... I went with the pipe
approach; using the sample code referred to by another
poster, it turned out to be pretty easy.

Thanks to everybody for your help!
