Yes, you're right, it behaves that way. It might very well be that
there indeed is a bug hidden (although it still makes interesting

There also is a flext/SndObj version on my disk that I worked on some
months ago but didn't finish. It has the same problem. I've put it on
http://footils.org/pkg/fbuzz-test.tgz (really unfinished, but should
compile on Linux)

I'd love it if you have a look at buzz, whichever version.
