Great article, and good reminder on using trace. Every time I rediscover trace, I can't remember how I ever forgot to use it in the first place for most of my problems.

I used CL in a production environment a while back for a threaded queue worker and nowadays as the app server for my turtl project, and I still have yet to run into problems. It seems like you guys managed to push the boundaries and find workable solutions, which is really great.

Thanks for the writeup!
