And it works. Really well. I'm sure you can agree. And yes, the Linux kernel development process blowes away all known "good practices" for how to design and develop software. Our rate of change for a stable kernel tree is HUGE! And people are noticing and starting to write thesis on how we do this, and why it is working out so well. I've given a number of talks on this topic in the past, see: http://www.kroah.com/linux/talks/ols_2004_kernel_devel_talk/index.html for an older one.
