Hi All, I've just published a blog post on lazy become and the partial read barrier<http://www.mirandabanda.org/cogblog/2013/09/13/lazy-become-and-a-partial-read-barrier/>in Spur. I'd really appreciate criticism, preferrably as comments on the blog page. This is one of the riskier parts of the design so it really does need to be pounded on. -- thanks, Eliot
