Hmm. Should this also have been marked for stable? I'm assuming that
the possible deadlock (strictly speaking it's a livelock, I guess?)
goes back several releases.

Anyway, it's in my tree now, I suspect it would be good to pick at
least as far back as it trivially applies.

Greg - commit b48f03b319ba78f3abf9a7044d1f436d8d90f4f9.
