Small point. Please don't knock the pollster ;-)

Polling trades CPU for latency gain. Polling is a high end solution for
low latency requirements, which covers a lot of my issues (not the
psychological ones though ;-)). Not so good for high throughput
systems, but it can be. A combined approach, poll for a while you can
then wait for an interrupt ( a bit like spin-locks ), can be especially
beneficial for supercomputer oriented frameworks as plenty of research

A polling, single threaded architecture is often best for the style of
performance oriented apps I develop. I have also seen some neat SAN
software developed with polling that wouldn't have otherwise worked at
all well.
