Yes, ptrace-over-utrace needs more work. But your message looks as if
utrace core is buggy, imho this is a bit unfair ;)
As Roland said, ptrace-over-utrace is not ready yet. If you mean that
utrace core should not be merged alone - this is another story.
But personally I understand why Roland sends utrace core before changing
ptrace.
Oleg.
