python-memcached was upgraded a week ago, so it's tempting to
revert it to see if it makes things more stable. What do people

The old one was very simple. Anyone recall why we upgraded it?

I believe it was to fix this bug:

Yeah, as Aaron notes, it was to fix an issue with the homepage for
Launchpad borking over memcached not returning data.  This was fixed
in the recent release.  I'm fine to roll back to the older release if
we think its required, but it would be better if we could sort out
what about the new python-memcached is causing this, if indeed it is.

Like William says, it's really the only thing that has changed around
memcached, so it seems suspect.  But it also isn't happening
consistently enough to really pin it on the upgrade, IMHO.

So I guess I'm a +0 on reverting. I'd rather we could work out what's
really going on, but in the absence of that, I'm willing to rollback
to see if the issues go away.

I'm seeing these pretty consistently on parallel test runs. It seems to affect both test environments. I filed bug 974632.
