I meant the actual target, that is, the bits this testsuite support
lets you test.  You haven't posted that, have you?

This is the sort of thing that makes me wish all our targets used
"target remote".  MDI isn't the only target interface that offers this
sort of thing, and it would be nice to have the enforced abstraction
barrier; that would make it easier to support the same thing,
consistently, on other targets.  Anyway, an example for MDI will
be almost as useful in practice.
