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.
