I had been thinking we'd have to wait a month or two for the buildfarm
to accumulate enough runs to be confident in whether the WSACleanup
removal fixes the ecpg failures. However, now that you did this
experiment, I think we have enough evidence already that it fixes it
(or at least makes things an order of magnitude better).
So now I'm inclined to not wait, but go ahead and backpatch 7d00a6b2d
now. There's still enough time before the November releases that we
can expect that any nasty problems will show up in the buildfarm
before we ship.
