I see, I split the patch series into the base infrastructure and the
x86_64 implementation, but I forgot to merge the two recipient lists.
:-(

Anyway, in the long term I would like to work on gradual decomposition
of the kernel into a core part and many self-contained components.
Sandbox mode is a useful tool to enforce isolation.

In its current form, sandbox mode is too limited for that, but I'm
trying to find some balance between "publish early" and reaching a
feature level where some concrete examples can be shown. I'd rather
fail fast than maintain hundreds of patches in an out-of-tree branch
before submitting (and failing anyway).
