There hasn't been nearly enough review or testing of this patch
series yet. Before a merge, it needs to be split up in smaller,
more digestable chunks for more comprehensive review, regression
testing and behavioural analysis.

There's probably only a handful of people who have done any testing
on the patchset so far, and given the widespread changes it needs a
lot more testing than this before we should consider merging any of

I really want to see this move forward too, but it changes lots of
critical infrastructure in subtle ways and so, IMO, this is not
a patchset we should be gung-ho about.
