The comment about '/dev/reads-and-writes-block-forever' intrigues me, as I think there could actually be lots of different use cases for this hypothetical '/dev/blocking' device. For instance, it could be used to intentionally plug the stdin of a process like described in the blog post. Another way that it could be beneficial would be debugging async yielding of blocking operations. Can't think of any better examples, am I totally off the hook?
