I was trying, and doing it right.  I had a small logical bug that was
breaking things and finally spotted it.

The difficulty there is that debugging requires so much work and the
documentation isn't explicit about these types of details.  So, just
needed some confirmation.  Nick's example in
http://www.apachetutor.com/dev/brigades helped confirm the behavior.

I'll leave an explanation why for my next question (rather than going
off on a tangent in this thread).  I'm moving beyond the basics with the
next bit, so please look for it.
