I'm looking through node.js which is a webserver with javascript code. So one of the cool features is that all of its commands are non-blocking! the server just keeps running. There is no mutex or multi-thread locks or deadlocks etc.
If you test it with ab command which is apache benchmark for webservers. ab already ships in Mac
$ ab -n 100 -c 100 http://127.0.0.1:8000/ # create 100 connections , 100 of which are simultaneous
This is ApacheBench, Version 2.3 <$Revision: 655654 $>
