This isn't the case from my reading: we *can* hook it up now?

Why this? It doesn't change anything with my gcc so I think
I'll revert that.

I just tried a `make run_vmtests' and it fell on its face.
There's a little comment in there saying "please run as root", but we
don't *want* that. The selftests should be runnable as non-root and
should, where unavoidable, emit a warning and proceed if elevated
permissions are required.
I tried running it as root and my workstation hung, requiring a reboot.
Won't be doing that again.
Dave, could you please have a dig at this sometime?
