Hi, Dmitry.  I think I disagree with this point.  I think that ideally
the test suite should be able to operate in a very minimal system, even
without a terminal.  Think of automated build daemons.  If the test
suite can provide some sort of terminal emulation for the things that
need it, that would potentially eliminate the need for the runner of the
test to provide it.  It may not be possible to completely abstract
everything away, but to the extent that we can we should.
