Hmm, it is unfortunate that a process ID of 0 is "verboten", since
that's what you are really looking at with "target kvm".  And it
should be possible for me to actually make all the running processes
visible as kernel "threads".

I guess your diff is right, although I'd prefer a less arbitrary ptid
to be used.  Would something like ptid_build(0, 1, 0) work?
