This is useful for several tests, so we should put it under the
utilities library for the entire autotest.

I don't think so, at least as far as I can see.

Will think about it. By the way, I have commited some minutes ago the
latest version of the virtio_console test. I have cobbled together the
original patch, the later fix, and I also fixed some bugs in the test
while I was at it (most of them stem from the fact that there were some
duplicated functions in one of the sender classes, that was left there
by mistake). I think the test upstream is in good shape, so please use
it when you plan on writing more tests, OK?
Thank you very much for the awesome work put on this test!
