Hm, I'm not sure that's really an improvement, but I pushed it like that
(and the other change along with it).

I found that the "expected value" was different in v11 than HEAD,
which surprised me.  It looks like the reason is that HEAD sets up
more/different RandomStates from the same seed than v11 did.  Not
sure if it's a good thing for this behavior to change across versions.
