Is this something we have to worry about these days?  I haven't
worried about it for a long time, and write real time multiplayer
games which demand unbuffered writes ....  Of course, things
would be different if I were sending gigabytes of video down the
pipe, but for the sort of small writes I am doing, I don't think
there is any performance problem at all.

Anybody got some benchmarks so we can find out?
