To avoid the trickiness that comes with introducing fifos to these
tests, in the next patch version I've followed the suggestion of Peff to
instead create d/f conflicts to create an error condition. It appears
that these tests are not particular to the exact error condition being
triggered and therefore d/f conflicts are much simpler to produce.

Thanks,
Justin
