Do we believe

  tests do a reasonable job e.g. of looking for an unused vnd, so this
  should be mostly ok?

  if tests interfere with a reasonable config, that's a bug?

I can add some caveats.   My real point is: If someone is going to run
the tests, do we mean:

  It's reasonable to run them on your system while it is up multiuser.


  It is not safe or reliable to run tests multiuser; boot the system
  into single-user mode before running tests.

It sounds like you are saying it's ok to run multiuser, and there might
be trouble, but if so that's reportable as a bug.
