Yeah, I'd noticed that.

That is, you can reproduce the failure on old branches? That lets
out a half-theory I'd had, which was that Andres' changes to make
the backend always run its socket in nonblock mode had had something
to do with it. (Those changes do represent a plausible reason why
SSL_shutdown might be returning WANT_READ/WANT_WRITE; but I'm not
in a hurry to add such code without evidence that it actually
happens and something useful would change if we retry.)
