Great explanation of an event driven web server. Helped me understand ome of the benefits of the mongrel2 architecture that separates the tasks needed to be done completely by using ØMQ as the mechanism to decouple the connection handling from the message handling of the request.

While asynchronous messaging is generally a good idea, using a messaging middleware seem to be an overkill. One should use smallest hammer for the job.

Thread is a wrong idea in the first place - by broking isolation of processes (share nothing principle) they brought in the whole new class of problems with locking and synchronization. Only threads that share nothing is a reasonable choice, but without sharing the whole concept makes no sense anymore. So there are kernel lightweight processes which seems to be good choice for offloading the blocking operations from the main loop.

BTW, Erlang does it right from the very beginning.)

0MQ isn't a messaging middleware. It's point to point (unless you build your own middleware).
