Looking at the test source code, it has a 60 second wait for the
emulator to print expected data on the serial port. My guess
would be that when running with a highly parallel make check
we're sometimes exceeding that 60 seconds. I don't see a
reason why my series would have affected this in a way that
only failed with sparc64 qtest, and none others.
