Why? What you just did was to turn the whole thing into a non-sleeping loop. If that's the case, simply call poll with a zero timeout, so it won't sleep, and call your callback at the end of each loop. No need to artificially introduce another file descriptor into the mix.
Mind you, I still don't understand WHY you'd want such a thing. This code will, by definition, consume 100% CPU all the time. Shachar
