If we go for extending clone3, I wonder whether we should also introduce a sigaltstack2/3 ;). I haven't checked what the current patches do and won't have time until early September (on holiday from the end of today).
The current patches (and the x86 stuff that's in -next) punt on sigaltstack for now, the discussions around that are unresolved. My hope is that whatever we come up with there can be cross platform.
