Asynchronous networking is all the rage now. lighttpd is completely  
asynchronous and VERY fast.

Have you heard about NodeJS? It uses asynchronous IO as the primary  
(only?) way to do IO. As closures are first-class JavaScript language  
features, async IO works pretty well there. I dream about creating  
something like this in D as well one day.

Anyway, the idea is that nothing should block your event loop for more  
than a millisecond or so. If something takes longer, then either you need  
to look into "asynchronizing" it (file access?), or putting it in a  
separate, isolated thread.
