We should special-case that one out, as it's only intended to be
used by our test cases. (In an ideal world we'd diagnose "you
used '-accel qtest' but didn't also pass '-qtest something'
to set up the communications channel with the test harness"
better than just SIGTERMing. But it's test code :-))
