Libmill/Libdill (go coroutines) are not on the AMPQ->ZeroMQ->Crossroads->Nanomsg (socket abstraction) path ; in fact, they have essentially nothing in common except sustrik.

Not to mention that this is obvious if you understand what the core of each thing is in terms of capabilities. If you are gonna be the "technically..." guy, at least do it right.
It's about decomposing things, which is the essence of good design, and - supposedly - the UNIX philosophy at its heart.
As an actual user of ZeroMQ, nanomsg and dabbler of libdill, I assure you I know what I am talking about. Libdill/libmill is NOT on the same arch. It could be used to implement the next generation of zeromq/nanomsg, but it does not, in fact, provide any functionality that these provide today - it would be an internal implementation detail if sustrik followed through on that comment. But it would not be a nanomsg rewrite, likely something completely new - nanomsg has been rewritten, several times in several ways, by Garret D'amore who has taken over. D'amore explicitly rejected using e.g. libuv (mentioned in that comment) as a basis for a nanomsg rewrite. There's an "uncertainty" principle at work here - separating of concerns generates dependencies which in the grand scheme of things are not necessarily good.
In fact, one of D'amore's rewrites used native OS threads in lieu of a co-routine library, which worked perfectly well on FreeBSD and Solaris, and abysmally on all other OSses. The main reason to use a coroutine library in a messaging library is actually that the underlying OS threads implementations scale so badly on most modern systems.
Commenting like this will get you banned on HN regardless of how much you know or how right you are. Please reread the site guidelines (linked at bottom of every HN page) and take them to heart from now on.
