Following https://golang.org/pkg/runtime/pprof/. When attempting to build
images in https://github.com/linuxkit/kubernetes CI the process is mysteriously
being SIGKILL'd, which I think might be down to OOMing due to the resource
limits placed on the build container.
I haven't done so yet but I'm intending to use these options to investigate and
they seem potentially useful in any case, even if this turns out to be a
red-herring.

- this is pretty much the smallest change to split this out and it
exposes a few things that can be improved later
- no change to logging yet
