Alas, I don't think it is. :(
I'd come to the same conclusion.
Oh, well, I'll keep looking...
I'll point out that the configparser test in question does a lot of
resizes. It may be that the problem only surfaces after many resizes
and apparently only for certain hash randomization seeds. At the
moment I'm looking at how hash randomization impacts resizing. I'm
certainly seeing that the resizes happen at different item counts
depending on the seed.
