That went in in 8b0b6303e. frogmouth had failed in 5 of the 23 HEAD runs
it made between 4e37b3e15 and 8b0b6303e. Since then, it has shown zero
failures in 50 runs. I don't know what confidence a statistician would
assign to the proposition that 8b0b6303e improved things, but this is good
enough for me. I'm going to go back-patch it.
