This doesn't qualify as a slow device unless it can be interrupted.
That means that you have to provide the appropriate framework for doing
so in select.cc like you see with other slow devices.  If/when you do
that we can make it slow again.

The problem that you're seeing is due to the fact that I forgot to move
the \dev\dsp string in path.cc.  I have rectified this.
