Goody. I'm working on a linux vritualisation project for IA64 (Linux-on-Linux, or LoL for short ... yes the acronym is chosen deliberately).
I also have some `ptrace improvement' patches. some are the same as yours (the one-shot syscall stop, for example).
One other that I found very useful for this kind of virtual machine, is being able to specify an address range for the IP for syscalls to stop on. So I can specify that the VM should stop only for syscalls in the virtual machine, not in the signal trampoline or in the hypervisro code.
You can get my patches from http://www.ertos.nicta.com.au/software/virtualisation/lol.pml
They're not quite ready for prime time yet, but are getting pretty close.
