This patchset is attached to the previous thread making it more complicated for me to process. This buries it deep in the mailbox and might interfere with applying entire sets. Is this the next version, so v3?

It's second on the mail lists, the first one was closed RFC. The first was without any version, i.e. v0, this one is v1 (should be v2). I promise to be more careful next series.
