OTOH, the Twisted approach avoids all the delicate synchronization
issues that arise when using threads to perform concurrent IO tasks.

Also, IO is by definition not CPU-intensive, so there is no point in
distributing IO to multiple cores (and it could even cause a small
decrease in performance because of inter-CPU communication overhead).
