That's not so. There is a clumsy prototype version. Much of the work to
do it properly is really just plain ptrace clean-up and not specifically
about using utrace. Oleg and I are ready to work on it as soon as our time
is not monopolized by trying to get the core utrace code to be accepted.

This ptrace work really buys nothing with immediate pay-off at all. It's a
real shame if its lack keeps people from actually looking at utrace itself.
(This has been a long conversation so far with zero discussion of the code.)
A collaboration with focus on what new things can be built, rather than on
reasons not to let the foundations be poured, would be a lovely thing.
