This point (2) is in fact not correct, at least according to what I
understood. My colleague Alexandre can confirm, but apparently,
per-package staging has only been very recently introduced in OE. And
yes, top-level parallel build was causing some spurious build failures.

Alex, if you have more details, we're interested :)
