Thanks for the tips Miles. One of them really hit home:
I love writing to stdout, and it's all over the place in my app.
It's great because you can run your scripts / apps as foreground and
get a live trace, or daemonized and it goes to the log file. Your
warning on this one sounds like the voice of experience, and I
believe it. But I'd like to understand the details.
Any ideas why this is a dangerous thing to do?
BTW. I don't know if lighty has a keepalive feature, but I'll look
into this. Sounds like it was the main issue for you, and it could
be for me too.
