Currently, xtra uses both a mpmc and mpsc channel, although the mpmc channel is one I implemented and maintain, barrage, so I would be willing to merge any changes that...

Alright, thanks. So, it would have a single hardware thread, and mostly channels would be used to communicate from different interrupt contexts/to the main context (if that makes sense)?

Hm, well regardless I would open an issue in `flume` first about no_std support (it's the underlying MPMC channel used by xtra currently). It _might_ fit into the async rework...

The user probably can find a way to use this extra info -- for instance, only displaying only logical CPUs. It might also matter for very low level stuff, or...

Spaad 0.3 is associated with xtra 0.4 whiuch is why this fails to compile. Spaad beta 0.4.0 is associated with xtra beta 0.5.0. I'll cut a release today for spaad...

I've released spaad 0.4.0 for xtra 0.5.0. > do you think each version of spaad would do well to depend on a the latest version of xtra itself? This *was*...

+1. How much code will this break?

Nice! That is very good. Will any *java* code break, or are the changes easily fixable?

That's cool. +1, definitely merge this
