Hi Will, sorry for the delay -- this has turned out to be more fractal
than I had hoped. :(

I think some of the fixes I'm working on are going to conflict with or
supersede portions of this series (e.g. portions of ptrace and signal
handling), and I'm aware of a couple more SME-specific issues that are
not addressed here.

I'll try to get that out in the next few days, and then look at this in
a bit more detail.

Rutland.
