Use of usleep does not automatically invalidate the test. However, looking at
the test source again, I see this is a different test case (and different bug
report) from the one I was thinking of, which claims the same issue (stolen
wakes). I had a conversation with the author of that other bug report and was
convinced it's valid; I'll have to go back and find it so that this report can
be considered as a possible duplicate...
