DOOM DOOM DOOM (a coro/thread kqueue-based scheduler)

I've created a new sub-project, code-named 'doom', for the coroutine-based cooperative threading system.  It uses kqueue(), of course.  Because it's better.  It wouldn't be too hard for someone from linux-land to make a version based on epoll.

In the doom directory, you'll find a simple http demo, and the obligatory echo server.

Exception handling certainly makes the code look a lot nicer.

I'm the best at space.
