utrace itself is just a kernel-level rework of the lowlevel bits behind
ptrace, it won't help you anything at all right now.  uprobes is very
basic infrastructure that in theory allows doing some kprobes-like
probes on userspace processes.  It would be a building block to
implement something like this, but in the current form is far from
what's needed.
