This is about the best and most well-balanced counter opinion I've heard
so far. Indeed, the zero-copy properties are more than nice.

I'll admit that I'm a bit extreme in this -- I'd sooner create a whole
infrastructure based on shared memory and signals to achieve zero-copy
communications between processes than just do what's obvious:  go
multi-threaded...! ;-)

I definitely plan to. I'm near release 0.9.2 which fixes some minor bugs
and a memory leak, and I'd love to package this one or the next.

Thing is, I'm not too familiar with the whole process and policies. I
love what these do for Debian, as I get to experience its advantages
almost daily, but need to learn a bit more about this.

I'd like to -- I live *very* near there. Where can I find more
information? It isn't announced as an event on debian.org.
