Oh, they're ancient, but they go with the Erlang Workshop paper
which is also included (doc/erlang07-wiger.pdf), and are still there for illustration
of some of the chapters in the paper.

What I did was integrate gproc into OTP, instrumenting the OTP behaviors
so that they would register properties informing about their characteristics.

I also patched gen_leader so that it would handle dynamic addition and 
removal of nodes, but that patch is not to be taken seriously! It was just for
demo purposes.

A problem with that approach was that many people thought gproc required
patches to both OTP and gen_leader, which was never true. :)
