I would be willing to add/replace the spopen model with polling. I sort
of tried to get part way there by scanning stderr, way back when I first
implemented spopen. I didn't really think about blocking at the time, I
just figured a 3rd party util that used stderr needed to at least note
that, usually by throwing a warning. 

I will look at transition/implementation issues later. I think this
souns like a 1.4 issue, however.

Thanks. I think most of this can go right into 1.3. Except I am hesitant
to add a new plugin at this point, so maybe check_cpu itself can get
added just after 1.3 is released.

Sound reasonable?
