Right, the point is precisely that some versions of rmtree() fail
to remove a mode-0 subdirectory.

I think the latter would be a very good idea, just so that this sort of
failure is less obscure. Not sure about whether a recursive chmod is
really going to be worth the cycles. (On the other hand, the normal
case should be that there's nothing there anyway, so maybe it's not
going to be costly.)
