Sorry, I've been preoccupied with personal matters for the past little
while, and hadn't had time to think about this. After a review of the
code it looks probably all right to me.

Well, it's only one failure, but it occurred after prairiedog had run
a grand total of 20 buildfarm cycles on 9.2 and newer, so I'm thinking
that the probability of failure on that machine is more than epsilon.
If we don't see it again for a good long while then I'll believe that
this fixed it.
