LGTM. I was the one who added the raise in the first place,
and I'm OK with removing it. Although I'd really like to
know *why* the client is disappearing in the tests (which
is why I added the raise initially to try and track it down).

It's intermittent, that's the problem. Mostly it doesn't
happen, I'd really like to know why it sometimes does :-(.
